The properties of solvents
WebbAbstract. Solvent polarity and the local environment have profound effects on the emission spectral properties of fluorophores. The effects of solvent polarity are one origin of the Stokes shift, which is one of the earliest observations in fluorescence. Emission spectra are easily measured, resulting in numerous publications on emission ... WebbA solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
