Introduction to Infrared Spectroscopy

[@michaelackerman8455]

Astonishing! Crystal clear, beautifully illustrated and presented.

[@mayurmankar3251]

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

[@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!!

[@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.

[@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

[@pajawallflower]

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

[@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

[@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.

[@stephaniegarcia8557]

Never understood the concept until now! Thank you so much!

[@dsiriman]

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

Wow! That's saying a lot. Thank you!

[@friendlydragon8999]

@@Knowbee your video is the best.i feel excited .

[@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.

[@daotianma1392]

Thanks for this! Every other video acts like we all should already know this stuff.

Best viduo ever, i watch the viduo every time i need to remember the info., thank u so much

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.

[@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 ?

[@mariokart6118]

Very clear tutorial

[@nicholasallen1798]

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

[@68-sarasultana54]

really helpful

[@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:)

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 ?
