5 years later and this video is still saving lives. I'm a first-year grad student taking inorganic for the second time going back to my senior year of undergrad, and this is by far the most easily followable, clear explanation regarding both the chemical theory and math behind character tables I've ever seen, especially when the current prof can't organize the class or explain topics for shit. My friend, you are doing a service to students of all levels with these guides!!

[@AllBoutChemistry]

I'm so glad to hear this
Wish you all the best for your preparation

[@mohanavani6011]

What a man who make a student to understand within 30 mins which was not understand after attending 6 hours class 😅😊very useful

[@abhikt1073]

Thank you for this video. Im about to take my Inorganic final in 12 hours and this helped fill in the gaps from lecture. You're a lifesaver, keep making more videos!

[@AmrEid]

Thank you very much! You're explaining in a very easy to understand way. I turly appreciate all the effort you're exerting in this channel.

[@alexb.5582]

I’ve watched upwards or 6 videos explaining irreducible representations in group theory, and this is by far the best explanation. Thank you!

[@AllBoutChemistry]

Thank you so much 😊

[@jayzepickle6637]

You are incredible. I was struggling with finding easy to digest information without a ton of random other things I dont need. I feel so prepared after watching this, thank you!!!

Hello sir, what if quadratic function is present only in A1 and absent in B1? Will it be still Raman active? Or just one of the term has to have quadratic function?
Thank you for the video.

[@AllBoutChemistry]

It should be present in any of them A1 or B1. In the case taken in this video luckily we got quadratic function in both of them. Bt if it would have been absent in B1 but present in A1 then also it would be Raman Active.

I don't have any expaining columns in my table and I have omega and omega^2 in my table and also a 3. Are the columns always the same in all tables or I don't understand. My whole table is just this:
V0 1 1 1 1
V1 1 w w^2 1
V2 1 w^2 w 1
V3 3 0 0 -1
where V0, ..., V3 are representations denoting the rows and I am asked to give the decomposition of the representation EndC(V3) into irreducible components. Pls help.

Your video was good. Just a correction that it is translational modes not transational. Translational modes arise when molecules move in a particular direction. Secondly you didn't explain how to look for the number of IR modes and Raman modes. I was looking for that in your video.

Is the value for the contribution of character per unshifted atom same for all the character tables(various point groups) in case of identity,inversion and reflection? or does it depend on the total number of atoms in the molecule?

[@AllBoutChemistry]

Contribution per atom remains same, but the value of number of unshifted atom changes depending upon the molecule
