Abstract
The KBM equation for determining solvent frequency shifts is generally useless for predicting vC = O frequencies for compounds in various solvent systems. The vC = O frequencies for acetone and tetramethylurea in various solvents do not correlate with dielectric effects (ε) of the solvent. A series of factors most likely determine the extent of solute/solvent-induced vibrational mode frequency shifts.Keywords
