CHARACTERISTIC VIBRATIONAL FREQUENCIES OF OXYGEN COMPOUNDS OF PHOSPHORUS AND CHLORINE: CORRELATION OF SYMMETRIC AND ASYMMETRIC STRETCHING FREQUENCIES OF PO AND ClO BONDS

Abstract

Linear relationships have been established between the symmetric and asymmetric stretching frequencies of PO₂ and ClO₂ groups that are useful in the assignment of the characteristic vibrational frequencies of these groups in the Raman and infrared spectra of phosphorus and chlorine compounds containing two or more oxygen ligands. The values of the frequencies depend, in a systematic manner, on the electronegativities of the groups attached to the central atom.
