Solvent effect on absorption spectroscopy and Difference between UV and Visible Spectroscopy

Solvent Effect
Solvents play an important role in UV spectra. Compound peak could be obscured by the solvent peak. So a most suitable solvent is one that does not itself get absorbed in the region under investigation. A solvent should be transparent in a particular region. A dilute solution of sample is always prepared for analysis. Most commonly used solvents are as follows.
