    Thanks for your video. I have a question. At 13:06, Ket was directly proportional to the spectral overlap integral J. What does it means? The overlap of the absorption spectrum of A and the emission spectrum of D? Hope you can help me.

    Thank you Michael, these videos are amazing. I am going to distribute them to my coworkers asap!
    One thing I am coninuously wondering is why 'singlet and triplet wavefunctions are orthogonal'.
    I cant seem to find the video where you introduce or explain this.
    I have a vague idea about the need for a source of angular momentum to interchange between them, but I'm confused about the distinction between geometrically orthogonal orbitals e.g., n and pi* and orthogonality of wavefunctions.
    Thanks again!

    Thank you so much for this video, it was really clear. But I was also wondering, how is it possible to differentiate FRET and Dexter? I guess it's with the help of some formula. Is there any other way to differentiate them? Thanks again for this video :)

      This is typically done using the distance dependence of the rate (or, equivalently, intensity) of energy transfer. Dexter ET falls off rapidly with distance, so if energy transfer is observed over relatively large distances (e.g. in a protein where the donor and acceptor are held far apart), it's assumed to involve FRET. Solution-phase ET between small molecules is usually assumed to be Dexter ET although it may not always be!

    Hi Michael, very nice lectures. I am preparing ppt on this myself and digging deep as a PhD student for a seminar. May I ask you on any additional literature suggestions? Any suggestions would be greatly appreciated!

    I cant believe that Trivial Energy Transfer was the bay harbour butcher
