    It’s kind of funny to me that I study chemistry with your videos and not with the stuff my teacher gave me in my native language. So thank you very much for teaching chemistry basically all around the world and I’m really glad I found your account.

    Thank you for this short yet full of useful knowledge of chemical bonding video and glad we're continuing with this wonderful series, hopefully the time lapse between releases will be shorter as we get more and more attached as we advance in this topic. What a gift to explain such complicated things so effortlessly and to deliver this content so clearly :)

    Perfect Timing. Got my final for my Grad Inorgo class and J-T Distortion were one of my weak points. Thanks much!

    finally a good explaination of the jahn teller effect! I could not comprehend it until now, finally someone explained it proper! thank you so much!

    Thanks man, I have a really solid inorganic chemistry professor but sometimes how she explains things to me just doesn't click. But this did it!

    Prof Dave will you make a video on SALCs (symmetry adapted linear combinations) and how character tables / projection operators can be used to work out the orbitals in ligand field theory? Also the relationship to Raman spectroscopy

    Thank you Dave!

      What's so funny about the fact there's no curve?
      I've lived in the Chicago area my entire life.
      On a clear day one can see over Lake Michigan from the Michigan shore to the Chicago skyline with as little as a decent binocular. Even better with a digital P900.
      Based on the "current" mathematical theory of the heliocentric model, the majority of the skyline should be below the horizon limits, however it's not. It can be seen to the bottom from Michigan.
      Explain that.....

    It is Queen englis thanks I can understand was afraid of indian english but every queen english chemistry explaination channel is worth to be recomended. Just like with Symplifing synthesis but whilst I only recomend 1 particular Vid on d-Orbital logand vonding from them, I consider subscribing to you.

    4:22 d9 configuration is same for both low spin and high spin, so why is only the former unsymmetrical and not the later?

    • @ashmitnegi3265
      @ashmitnegi3265 ปีที่แล้ว +1

      i think it appears in all of the unsymmetric cases but those are the more common ones

    Talking about the Jahn Teller Effect, how do i know if the dz or dx2y2 orbital is the higher/ lower orbital?

    Prof, I don't think you could comprehend how excited i am for your debate with the flat earth conman. From my understanding, he already agreed. My biggest gripe is with his constant misrepresentation of Einstein and his theories. Other than that, great video as always.

  • @neomahlangu8728

    QUESTION: on the one slide where you show the specific spin states that will result in JT distortion, is there any significance in the colours? Do all the ones in black also undergo JT distortion??

  • @meike6999
    @meike6999 2 ปีที่แล้ว +1

    Dear Dave, thanks for the explanation. May I ask a (maybe stupid) question... since I have problems putting the bits together. Why are we considering all these energy changes in the orbitals of the metal when they are eventually being paired with the orbitals of the ligands to form MOs anyways? What does all of the eg ans t2g (and Jahn Teller splittet) levels mean for those MOs?

    • @jamiesonpeacock4338
      @jamiesonpeacock4338 ปีที่แล้ว +1

      Well, consider the MO diagram at 3:15. The HOMO and LUMO of the coordination complexes are typically the metal centre's d-orbitals, as shown.

    Copper is a shill element invented by Jahn Teller simply because undergraduate chemistry wasn't hard enough

  • @sarah_kyu7953

    But how do I know if have to put the electron in the dx^2-y^2 or in the dz^2?

  • @thebluebeyond2329
    @thebluebeyond2329 ปีที่แล้ว +1

    This could have helped but only if there was enough labelling of the orbitals.

    looks like 4 vertices in vertice V = 2 - Edges + Face rounded 3.14 face angle sum is scalable Euler invariant formulae (2) transition from Euclidean to nonEuclidean curved Face.....Yes or No?

  • @saisathvik3587

    Why no effect in symmetric arrangement?

    • @0rchidya
      @0rchidya ปีที่แล้ว

      cause simmetry means stability and the system doesn't need to stabilize so it doesn't have distortion

    Hey I’m here because you turned comments off on a video about transgender theory and I wanted to say something about it. For one I’m glad you made the distinction that gender is not a social construct, because I had mixed it in with the gender roles themselves and I have been calling gender a social construct as well. Also, I disagree on your assertion that comedy shouldn’t be focused on in the conversation. Most times I agree but there are some cases where it can start to normalize anti trans talking points. The example where Dave yells it was a trans after someone threw something at him is a good example of good comedy. But then in a Netflix special you get Dave Saying he’s team TERF. On the one hand you got Dave making a joke and reacting to a situation, and on the other is a planned joke that normalizes an anti trans hate movement. Sorry about invading this video to talk about a different 6 month old video, but you made some great points I wanted to thank you for, and I really wanted to voice my disagreement towards it to you.
