Vibrational spectra, force constants and conformations of molecules of trivalent tricoordinate phosphorus compounds

Data on the interpretation of the IR and Raman spectra based on normal coordinate analysis, on the force constants and on the conformations of the molecules of trivalent tricoordinate phosphorus compounds are summarised. The existing correlations between the spectra and molecular structures are refined and some new correlations are proposed. The bibliography includes 171 references.
