Polarity absorptivity +_+

  1. Jan 11, 2004 #1
    changing absorptivity

    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??

    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....
