polarity absorptivity +_+

[schordinger]

Solvent polarity would affect the wavelength of max absorption peak, but how??

and How the solvent affect the absorption coefficient??

is that related sth called Franck-Condon factor??

Also, Flourescent quantum yield also depend on the solvent polarity??
How?? and Why??

Thx

I am really confuse that why some compound would fluoresce stronger in polar environment (solvent) than non-polar solvent, like Fluorescein, and some other compound, like Acrylodan would fluoresce stronger in Non-polar environment......??


It seem that Fluorescein is a interesting compound....
