Infrared spectroscopy is an important technique in organic chemistry. It is an easy way to identify the presence of certain functional groups in a molecule. Also, one can use the unique collection of absorption bands to confirm the identity of a pure compound or to detect the presence of specific impurities.
In this video we are discussing about FTIR spectrometer which is used to perform this technique, also Components of FTIR, and FTIR instrumentation working in brief.
First component of FTIR is IR radiation source, which sends the source energy through an interferometer and onto the sample. In every scan, all source radiation gets to the sample! The interferometer is a fundamentally different piece of equipment . The light passes through a beamsplitter, which sends the light in two directions at right angles. One beam goes to a stationary mirror then back to the beamsplitter. The other goes to a moving mirror. The motion of the mirror makes the total path length variable versus that taken by the stationary-mirror beam. When the two meet up again at the beamsplitter, they recombine, but the difference in path lengths creates constructive and destructive interference: an interferogram:
The recombined beam passes through the sample. The sample absorbs all the different wavelengths characteristic of its spectrum, and this subtracts specific wavelengths from the interferogram. The detector now reports variation in energy versus time for all wavelengths simultaneously.
Energy versus time is an odd way to record a spectrum, so for easy interpretation we uses a mathematical function called a Fourier transform which allows us to convert an intensity-vs.-time spectrum into an intensity-vs.-frequency spectrum. which we can interpret easily.

You are great... Mam...💖
Really amazing explanantion. Wonder.. 👍
Love you mam you are my teacher respect from Pakistan
Mam mai iti ka student tha. mai abhi maruti suzuki me apprentice kar raha hu (quality department me). toh mai ye sab machine chalta hu. Like ftir,dsc,tga,utm etc. Par mujhe inki piche ki sci nhi pata thi ki kese kaam krti hai mujhe run krna aati hai But apki video se mai aab saari chije smjh raha hu (thanx mam )aap asi hi video dalte raho...👍

amazing explanation thank you mam for the video
Well explained and easily to understand
How to read the interferogram ?its totally new for me, By the way, the way you teach and clearing the points was great.
Everyday I learn more and in easy way ...thanku so much ...😀 Mem

Flawless explanation ma'am! Very handy. But I'd insist on keeping it in all English in future videos.
U r a very nice teacher mam ...
Thanks ma'am nicely explained...
Thankyou so much mam....i finally understood what the whole thing is about....respect for you mam....Mam please if you could make a vedio on XRD as well it would be of great help....Thankyou once again
Explanation is very good

Nicely explained👌🏻..Mam please make videos on how to interpret XRD, XPS, EDAX, SAED, Raman , Cyclic voltammetry and Galvanostatic charge discharge spectroscopic graphs
Very beautifully explained
Very helpful,thank you mam
This application most useful in Automotive - IC Engines for calibration / analyzing emission - exhaust gases etc. and more
good video keep doing these kind of videos
Thank you mam You made my today in exam ❤️❤️

Nice explain well-done
thanks mam for information
It's nice to understand, thanks,. When we can use FTIR?
Thanks ma'am.....
1) Same distance from beam Splitter :constructive interference 2) Difference in distance: destructive interference, is it compulsory the distance is half integral always for destructive interference,what if for eg it has difference of Lambda/ 5 is it still form destructive interference
Very helpful
Aapse request hai ki. Aap spectroscopy ke har chote aur Bade Concept Explain Kijiye.. 😊
Nicely explained
Mam tumhi khup bhari shikvta
Very nice mam . Please upload more videos
