Introduction to Infrared Spectroscopy

[@mayurmankar3251]

This is the best video on IR spectroscopy I have come across. Amazing video whole 15 minutes is investment.

[@michaelackerman8455]

Astonishing! Crystal clear, beautifully illustrated and presented.

[@johndavid1773]

this is hands down the best chemistry channel i have every encountered. you're incredible, keep doing what your doing. the understanding i gain from your videos makes me enjoy my work so much more, im gonna recommend to all my teachers

[@arlonathan9294]

I know im randomly asking but does anyone know of a tool to get back into an Instagram account? I somehow lost my password. I would love any help you can offer me!

[@dennessadaylan9936]

You provide the most simple, yet very informative and direct IR spectroscopy video. I wished i watched this sooner. It really helped me understand its usage for my final year project. GBU sir!!

[@elp09bm1]

I am reluctant to write comments but oh my God this is an awesome explanation of something which I was not able to comprehend for ages given that I have never learnt Chemistry.

[@amnasiddique8645]

best organic chemistry teacher i have ever get

[@KCJacksonProductions]

This saved me a hell of a lot of time and hair-pulling working out how NIRS can check BOLD response data.Thank you.

[@monxampion6930]

ive watched about 20 videos on this topic and i finally understand it thanks to yout video!! you explained this in such a smple way, everything makes sense now. THANK YOU

[@pajawallflower]

Very easy to understand especially when you know nothing. Thank you for explaining everything you talking about. Very good for beginners.

[@adiprai2887]

Excellent! Your approach of delivering concept is 5of 5 stars- simple language, good visual effects and and animations. Hats off to maker/ producers. I watched about 8 videos so far(stumbled on the videos lately) and they all impressed me. Keep going and looking forward to seeing more video lessons.

[@Pradeepa-wt5cy]

I thought I never gonna understand IR, Thank you so much you taught what professors fails to do.

[@fatimakhan-ei5fy]

Damn how beautifully and smoothly you have explained everything. It was so soothing to watch and hear. Just Love it.

This guy is amazing, he has a way of explaining complex processes as if there were a walk in the park.

[@ankitdedha6516]

great job man!!! this is the best introductory video available on the topic!

[@matarts9020]

Excellent, I´m studyng about green house efect and this give clearness about the vibration modes and the spectrography

[@ChristianoSts]

nice video. however, there´s one rule to consider about the absorption of light: 1- the IR only shows absorption when there is change in the dipole moment of molecule; and 2: Photon energy must equal the difference between energy levels. Classically the harmonic oscillator can have any energy. Quantum mechanically it only has discrete equally spaced energy levels given by Ev = (v + 1/2) hf. v = 0,1,2,... Selection rule: Absorption of light only occurs for ∆v = ± 1This means that each transition has the same energy change.

[@chemtutorpk9687]

Awesomeeeee! Keep going sir. You are the best

Jesus loves you ❤️ Please repent and turn to him and receive Salvation before it is too late. The end times written about in the Bible are already happening in the world. Jesus is the son of God and he died for our sins on the cross and God raised him from the dead on the third day. Jesus is waiting for you with open arms but time is running out. Please repent and turn to him before it is too late. Accept Jesus into your heart and invite him to be Lord and saviour of your life and confess and believe that Jesus is Lord, that he died for your sins on the cross and that God raised him from the dead. Confess that you are a sinner in need of God's Grace and ask God to forgive you for all your sins through Jesus. Jesus loves you. Nothing can compare to how he loves you. When he hung on that cross, he thought of you. As they tore open his back, he thought of your prayer time with him. As the thorns dug into his head, he thought of you spending time in the word of God. As the spears went into his side, he imagined embracing you in heaven. Jesus longs to be with you. Please repent and turn to him and receive Salvation before it is too late.

[@manuelsantos7807]

Thanks for upload this video! Sr.what is the software that do you use to edit your graphs and perform the animations?

[@swan2799]

A quick question, why the molecule absorbs the light matching the frequency of wagging/bending? So far I was thinking it absorbs only if the energy of the source light (of course having a specific frequency) matches the difference between energy levels of a certain atom in the molecule. Which way of thinking make sense?

[@iamvengeance3329]

Great Explanation ! Just one question : Why in the plot of amount of light transmitted vs wavenumber, the wavenumber decreases from left to right ?

[@naderdawood5972]

Why did you not just use the actual frequency at which the carbonyl absorbs IR in the example?

[@diamondk6214]

If you use ATR-FTIR that means that you won't have transmittance in y axis but absorbance and then you would have the opposite graph? this is how you basically get the spectra from ATR? I would appreciate if you could answer:)

You say all carbons are the same and thus vibrate the same, but what about isotopes of an atom? Does a carbon 13 have a different IR reading than a carbon 14?

[@rubayettanveer3479]

Top class explanation. Keep is up.

[@zeinabraslan8288]

What a great lecture! 👍👍

[@rinkudabas4077]

sir...why will not molecule absord light at 1 hz or 3 hz.... by absorbing .. it could have vibrated 1 time or 3 time per second... why it chose to absorb 2 hz and 4 hz only ?

[@christabelnimako2618]

Well explained. Thank you sir

Sir.. why frequency is not put on x axis but wavenumber?

[@jahanararahman847]

[@ramanujasrinivasans1898]

wavenumber=1/lambda (spatial frequency) is nothing but [frequency(C/lambda) / C(speed of light)].....yielding 1/LAMBDA they used this because frequency is always been a large number say in the form of 10^14 like that. so to make it look like a convenient they divided it by the constant C and named it spatial frequency....

[@haya4895]

thank you so but why the wave number is used instead of frequency?

[@haya4895]

@FMA B thanx alot, i will look for that As i understand from u , for each wave length there is different energy levels? So wave numbers distinguish between them? What i know so far is that each lambda is associated with one energy level.

[@haya4895]

@FMA B much appreciated!
