Abstract
The linear solvation energy relationship (LSER) concept is shown to apply to i.r. spectra. Solvatochromic shifts of a variety of X = O, C–Cl, and O–H ⋯ B stretching frequencies and solvent effects on absorption intensities are linear with solvent π*-values. Values of s in the solvatochromic equation, ν=ν0+sπ*, are related to chromophore structures.
