I'm preparing for GATE Physics and found your video to be exceptionally brilliant to grasp the concept behind modes of vibrations and their subsequent changes in polarizability resulting in Raman active/inactive. Thanks.

Sir u r osm.....all the lectures on spectro is very usefull for me..topis of Microwave ,IR and Raman spectro are very closely releted to M.Sc. Syllabus...so ty sir for u r tremandous work

Sir please upload Vibrational raman spectra and rotational raman spectra topic soon......

Sir, in banwell bending mode graph and asymmetric streching graphs are opposite of what you made in this video.. Apart from that all lectures were very useful. Thankyou😊

Kya samjya sir , awesome really awesome , thank u sir

Can't explain how helpful You've been for Me Sir! Loads of blessings for You! ❤

Outstanding teacher you are sir. Very thanks to you sir , love you sir from my heart.

Nice video👌👌 Simple language video Nd reason behind every thing is easy to understand... because of chemistry untold

Sir you're amazing.All doubts regarding Raman Spectroscopy has been cleared.Thank you very much sir.

Very very very beneficial video thank you so much sir 🙏, I'm medical student, so ye chije thodi si complicated hoti h hme smgne k liye , time lgta h thoda concept clear krne me, but aapki videos ne bhoooooottt hi jyada ache se pure topic ko clear kr diya , bhot easy way se smgaya, seriously sir , your explanation is toooooo... Good 👍👍👍👍❤️

Sir aap to God level kaa teacher..ho..is Chee's ko reference book see study karne ki zaroorat hi nahi hii mujhe.....just amazing u r..that's wt I can say.....and pls make a video on the topic..application of IR and RAMAN in structural ellucidation..

the way you explained i have never seen this type of expldination by any one thnku yogi sir

Awesome ,woww this is chemistry untold that not everybody tell you, thnkuuuu sirrr , I remembered those days of my masters when whole class used to sleep in this topic, thnkuuuu very much

Your lectures are full of energy (vibrational. rotational and translational) and it's so alluring at times that I have to complete all your videos in one sitting...Respect for the way you teach. i am glad that I came across your videos. We need more people like you...

I am watching your videos for first time and just loved the way you are delivering your lecture 👌

It's an amazing class And also very informative We can easily understand raman spectroscopy simply and detailed. Thank you so much sir

During my M.Sc. I didn't understood this topic....I felt like it was so boring....but it is actually so much interesting and sir you make it as easy as anybody could understand

i understand this chapter after watching your video before this i am zero in spectroscopy.

Sir you are a brilliant teacher and your teaching style is very very interesting .😊😊😊😊🙏😊😊😊

Great teaching skill!

Thanku so much sir,your hard work makes thing easy to understood.

Thank you soo much sir... Thank you again for this masterpiece playlist... Though I'm the student of physics at First i wasn’t wanted to watch this as this channel teach about chemistry but i watched Your 7 vdos just because of your way of teachings, and get benefited ❤ #respect

Always helpful for me...thanks a lot.

Dear Sir, I do have a question and I hope you reply to it. It is known that every molecule in the universe has some rotation or vibration to it. Now, if they are vibrating, then that means that there will be some change in the polarizability. Even though it can be extremely small like in the case of CO2, it still had a little bit of change and hence showed Raman low intensity peaks. In the previous lectures you said that 99% of the time, the photon hits a molecule and elastic collisions occur so its Rayleigh scattering. The Question is, If every molecule is vibrating and having a slight change in the polarizability no matter how small and showing a low intensity Raman peak why did we say that only one in a million molecules will actually show Raman Scattering? What is the criteria? Should not every molecule (as it is vibrating) have some change in the atleast one of their vibration states and hence show raman scattering? Kindly do explain I shall be Grateful. Regards, Zulkifle Ikram.

Sir your lectures are very informative, very useful and i cant express in words thank you

Fan of your hard work

Awesome sir

Really a masterpiece... go-ahead sir

Thank you very much sir... Brilliantly explain everything... Accepts our bundles of love from Pakistan 🇵🇰 😂😍 😍

superb ....... thats a new concept

Outstanding mindblowing sir thanks a lot.

Awesome👍👏😊...

Sir lajwab apka koi jawab nhi smjhane style to ekdm dhasu ha

Thanku sir boht achi class thi.... God bless u sir... Rise high

Sir pls upload a video on structure determination by Raman spectroscopy

Excellent explanation thanku

Thanks a lot sir❤️ you are impressive

jst wonderful!!

Thank you so much sir 🙏🙏🙏😊

Excellent brother you are great

Very neat explanations. Thank you sir :)

Sir this is Very very interesting video...it is also very informative.

nice explain 😊sir ,great

Uff, kitna syllabus hei ...sara din padna padega

Really a very nice video😍

Nice workkkk sirrrr. No wordzssss

Best explanation ever.

Outstanding 👌👌👌

Thank you so much you gave learnt a lot in shortly in raman spectroscopy .... i request to you sir if you make video on RRS and CARS in raman spectroscopy then its very great ful for us...

Great job brother

Nice explain sir 👍👍👍

It is a nice talk. Just one thing I want to clear, in all these cases where the stokes anti stokes line? The peaks we get in raman spectra , what is the relation with all of these with the basic of raman Spectroscopy, the stokes and anti stokes line.?

Thank you so much sir.😄

You are not a border army you are inner of outer border army , nice social service 🌹

Awesome video sir

Thank you so much sir your explanation too good Sir please making vedio on group theroy....

waiting for your all videos

Outstanding sir u have soo much of knowledge ..... sir plz make video on organic reagents n naming reactions....😊

sir graph for bending mode and asymmetric mode are opposite from as you drawn in viedo

Sir, PLZZ complete chemical kinetics...

first of all, I have to say that you are a wonderful teacher .... sir I have one doubt please clear if you can that is regarding bending vibration of CO2 and its graph between α and displacement .... it is in downwards direction or in an upward direction as there is a difference in your and Banwell book explanation .....your explanation looks good but I request you if you can clear the doubt

I don't understand anything even after completion of MSc in Physics. But i clearly understand about Spectroscopy.. Thank you very much Sir🙏

Seen full series of NMR and Raman spectroscopy..

SHUKRIYA SIR

Superb explanation

superb explanation sir plz make video on pure rotation raman spectra

sir..aap ka padha na style bahat acha laga au apka video hamare li bahat helpful he sir..plz..NMR & electronic spectroscopy ka video upload kijiye

Sir, Quality of your video is too good. Great effort. Can you make videos in English ? If you can, it will be useful for many

Sir u are great

Sir, I have a confusion, do you have Spectroscopy book by Banwell, then please see page no. 111, in which you can see that the graphs for bending modes and asymmetric stretching mode do not match with the graphs shown by you. Please tell me which one is right, your one or the book's one. Please reply Sir.

Waiting for your valuable reply

Thank you so much sir, I have one doubt, that whatever Raman shift spectra is gain,that's for one molecule only ? and we got stokes antistokes and Rayleigh lines, So whatever difference occur in emitted radiation , is this happen at a same time of different vibrational and rotational modes of molecule to generate these three different types of lines?

Wow nice sir
