Abstract

Abstract The I.R. and Raman spectra of K 4P 4S 8 · 2H 2O and (NH 4) 4P 4S 8 · 2H 2O have been recorded and the vibrations of the anion have been assigned for D 4 h symmetry. A normal coordinate analysis has been performed, and agreement between observed and calculated frequencies has been achieved by employing “standard” values for the PP and PS force constants, 2.05 and 2.8 [10 2 N m−1], respectively.
