2.6 Energy Differences Between Singlet and Triplet States

[@e-alf-1]

Excellent information, I work with TADF materials in my PhD

[@mevansthechemist]

Awesome! I'm fascinated by the work going on in that area.

Amazing presentation and explanations -- is it possible to provide a link to the paper/review you reference about the exchange interaction?

[@mevansthechemist]

Looks like that's just linked to the Wikipedia page on exchange interaction: en.wikipedia.org/wiki/Exchange_interaction. It's a nice discussion there, though!

This is also a fantastic treatment: www.cond-mat.de/events/correl12/manuscripts/koch.pdf.

@@mevansthechemist Thank you again for your amazing content and for sending the link to the paper -- I miss computational chem and photochem and physical organic chemistry and you help bring back all that latent joy

Thanks a lot for the incredibly explicate video, it guess it cannot be clearer than that ;). Somehow I cannot find the link to the paper you mention. Am I missing something or it is not there? Thanks again

Hi, thanks for easy to understanding explanation. It was very helpful to me. I've got an one remaining question though. You explained the singlet and triplet state energy gap(Est) as because the direction of Sz. But there is one case of opposite direction of Sz in triplet state. Then how can I explain the reason of Est between "in-phase" triplet and "out-phase" singlet state? And according to your explanation, is there an energy gap between "alpha,alpha triplet" and "alpha,beta triplet" even if there is no external magnetic field?

there is a difference between paulis principle and paulis principle deals with exhange integral and fermions being anti symmetric
