- Description-Chemical infrared spectroscopy emerged as a science in the 1880s. In the 1890s, A. A. Michelson, to further his studies of the speed of light, invented the interferometer. In the early 1940s, chemical infrared spectroscopy was still an immature scientific field. But with the commercial development of the optical null dispersive spectrophotometer, later that decade, chemical infrared spectroscopy came into widespread use. Dispersive instruments proved the tremendous value of infrared analysis, and soon became the mainstay of organic characterization laboratories. In 1949 astrophysicist Peter Fellgett used an interferometer to measure light from celestial bodies and produced the first Fourier transform infrared spectrum. But for many years, only a few advanced research groups with access to large, expensive computers and with personnel able to wait up to 12 hours to transform an interferogram into a spectrum used Fourier transform infrared (FTIR) spectroscopy. For two decades more, FTIR spectrometers were limited to studying problems not solvable with dispersive techniques. In the late 1960s when microcomputers able to do the Fourier transform became available, commercial FTIR spectrometers appeared. The 1966 development of the Cooley-Tukey algorithm, which quickly does a Fourier transform (the Fast Fourier Transform or FFT), was also instrumental in the commercialization of FTIR spectrometers. However, the first FTIR spectrometers were large and expensive and were found primarily in a few well-to-do research labs. Gradually, the technology reduced the cost, increased availability, and enhanced the capabilities of FTIR spectroscopy systems. The performance-to-price ratio provided by FTIR spectrometers today was unthinkable only a decade ago.

Hello Sir,
Thank you for this practical demonstration of FTIR.
Keep it up your work.
Dont use mouth air otherwise KBr will take moisture due to hygroscopic material.... Most important is that KBr should be dry
Thankuu so much sir bohot helpfull hai
Actually I'm preparing for interview
Thank you very much.
Good information
Well done Sir
Very nice sir
great job
Nice one...
Excellent👍👏.
Sur ur way of explanation is really awesome, if possible upload videos on interpretation of ftir data n x ray diffraction
Good
Nice sir
Which FTIR Device is better to purchase? Make and model
Kdk
Thank you sir ji
Please share to others.
Sir plzz tell me Why do we use KBr and why not NaCl or any other compound to prepare Pellets
Sir
While cleaning can we used other solvent like acetone it will evaporate easily???
Why dont u use the dried kbr...otherwise it absorbs the moisture..
Hello sir
How can I identify the solvent of hexagonal boron nitride metal matrix nanocomposites
Pukh marne se moisture laka hoga CO2 peak bi show hoga
👍👍👍👍
Me bhi Aaj se pharmaceutical company me ftir learning kar rha
Rha hu
How to analyse liquid sample in this instrument plz tell me .i have this model in my organisation
Good afternoon sir
Sir training fee structure kya hai
What is role of resolution here?
If sample is unkown how we can calibarate and detect sir
Aslam o Alikum Sir, Karl Fischer ko operate kasai kia jata hai
Sir side me dustbin h ya jmeen me fek rhe 😁
Hiegher WN side spectrum energy is less need to be alligne DRS assy
How we can calibration of FTIR?
By polystrene Film
This video is not playing.giving error . I have tried a lot.
I also try wait for some time.
video is playing plz watch again.
@@prof.karanajaygupta thanks
Sir,FTIR calibration kaise karte hai? video please🙏
Polystrene Film
Vh pata he lekin video.
Sir, the video is not playing. Giving error.
Ok I will check.
video is playing plz watch again.
@@prof.karanajaygupta sure
Sir mai PhD student hun,mera research FTIR se related hai, aap ka mobile no chahiye
Sir clear software chalo
Methanol ko open kon rakhta h
Appreciate atleast you're getting the content.
Sir hum sbsa phala kisi be sample ko autozero ku krta ha 😅
Kyuki kbr khud bhi kuch radiations absorb krta h woh phale hi pta krne k liye
Bkg ka meaning kya h sir
Mens KBr ( potassium bromide) in next part I clear more doubts.
Bkg puchha sir KBR nahi.
@@girasegopal5323 Bkg means Background
