Solvent and UV/V spec

    Ah this is a question because I'm new to UV/V spec.
    What would a solvent do to a spectra of a compound when it is analyzed?

    Such as a polar/non nonpolar solvent on benzophenone?

    solvents such as:
    Nonpolar :Ethanol, Cyclohexane, n-Hexane
    Polar: Methylene chloride

    I looked online but couldn't find a simple description of things that would occur.

    I do think that the solvents could produce additional peaks on the spectra due to it absorbing/reflecting at certain wavelengths but other than that I'm not sure.

    Thanks alot :smile:

    I remember something along the lines of solvent broadening - increasing the bandwidth of the peaks - , along with something with do with shifts , or perhaps reflection ... Instrumental Analysis by Skoog should help , I'm going read upon this topic and answer your question when I have time.
