This document discusses solvent effects on UV-visible spectroscopy. It commences by explaining that UV spectra are frequently measured in dilute remedies working with solvents which might be transparent during the wavelength selection and don't interact strongly Using the solute. Prevalent solvents outlined are ethanol, hexane, and drinking water.S
