The theoretical investigation of sum and difference frequency generation in thin surface layers with rotational symmetry leads to formulas which connect the generated light intensities to the surface second order nonlinear susceptibility tensor. A maximum of seven tensor components can be determined
We agree with Kawski and Bojarski [1] that the correct value of dipole moment can be estimated from G 2 group of solvents where there is minimal solute-solvent interaction. However, if there is an intramolecular charge transfer (e.g. in aprotic polar solvents), the emission may be quite red shifted
