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.

Ah okay then.
Thank you GCT :smile:
