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.

Please make videos on polarimeter (specific optical rotation) and Water content analyser .

[@ashutoshsharma9012]

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

[@Vivek-bq7rb]

Nicely explained👌🏻..Mam please make videos on how to interpret XRD, XPS, EDAX, SAED, Raman , Cyclic voltammetry and Galvanostatic charge discharge spectroscopic graphs

[@kamalashraf806]

salam. light jo sample absorb karta Hai or vibrations(streching/bending) show karta iska result hota hai mtlb is say humen kia pta chalta hai ya isko ignore kar dety hain hum?... or kia sirf transmittance say he humen molecule ki identify/structure/functional group pta chalta hai ya phir vibrations b koi role play karti hen?

[@sreenivasarao5932]

Really amazing explanantion. Wonder.. 👍

[@shahrukhhanif5386]

Mam what is difference between frequency domain and time domain .....and why we convert into time domain from frequency domain

Everyday I learn more and in easy way ...thanku so much ...😀 Mem

[@BaaYo]

Thanks Akansha :)

[@Akshayfrancisk441]

Madam a doubt Why bending is only in finger region Also, how can we identify whether there is bending or there is stretching Also, does the functional group only show stretching

[@adityak3539]

Nice lecture, can you please answer this what is the wavenumber range for long-chain and short-chain molecules?

[@akshayasanthosh6056]

U r a very nice teacher mam ...

[@zahranoor4130]

Mam plxx anawer me why we used monochromator in uv before the sample while in FTiR it is present in behind the sample??

[@rashminair5435]

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

[@hommieez324]

Very nice video you are the best at teaching👍

[@RahulTiwari-fw3eg]

Mam isko likhenge kis tarah if question arise”describe const and working of ftir “ plz suggest.thanx mam

[@soumyaranjanratha2927]

Mam we are sending light on the sample.. Then light is nothing but a high intensity light then instead of these we can use laser or any other intensed light... As we have to project light on sample and we have to get graph...

[@BaaYo]

no here we are disscussing about IR (Infrared) light only...we use IR light ( Part of Electromagnetic radiation), thatswhy we call it FTIR (FT Infrared Spectroscopy)

[@ashhvinikamble-gaikwad8623]

Kindly make a video on NIR Spectroscopy

[@nilanjanachoudhury3058]

Ma'am it would be of great help if you could kindly make a video on XRF & XRD.

factor affecting c double bond o stretching vibration in FTIR?

[@abhishekkansal6986]

very helpful, plz make some vedio on solvent casting, Particle leaching,TIPS, freeze drying...

[@magnifiedmicrons]

You should have also explained why at the first place is there use of producing High and low intensity IR ?

[@jitubhatt69]

Mam pl.give information about FT-NIR

[@worldfitnessgoal]

Ftir spectrum is also known as time doman spectrum h because FTIR aquires tha data less than a second and it is possible to collect the many interferogram of the sample in very less amount of time

[@physicshub4637]

Very easy way of delivering lecture , it's very helpful

[@vijaykumarsagar12]

[@pritikapatil9064]

Hello ma'am your all videos are awesome 😊 can you do one video on ph meter working principle?

[@yashghodke5693]

when OPD is 2lambda then is the intensity of those two beam will be same or different? will the increased distance lower the intensity of beam which is reflected through moving mirror?

[@EFTcoach111]

There will be constructive interference, there r only 2 possibilities here either in phase or out of phase, it does not matters which beam came 1st,it matters how much distance it travelled, hence only the phase will be taken into consideration as waves r continuous

[@jannafatima6724]

Mam aik request hai ap sy kindly ap Mass analyzer py bhi vdeoa bnay quadrapole ion trap quadrapole mass analyzer y waly plzzz mam its a humble request

[@maahii8335]

Plz maam make a video on applications of ultrasound and nanotechnology in food analysis

[@faisalplays7237]

Ma'am can we say that in FTIR there should always be constructive? interference otherwise the radiation will not have intensity

[@einstenfaradayreddy2345]

Scientist madam are you expert in spectroscopy may be there is a chance to mix research in application in Bio

[@jatinbabariya8573]

What is deference between IR spectroscopy and FTIR. Working is both spectroscopy is same then why we use FTIR???

[@Zul_qar_nayn_]

Does mirror reflect ir

[@shrutikachaudhary672]

Very beautifully explained
