Force constant calculations for pyramidal four-atom molecules—II Pyramidal ZXY2 molecules CH3AsX2 and (CH3)2AsX (X Cl, Br)
General valence force constants of CH3AsX2 and (CH3)2AsX (with X Cl, Br) have been derived from the experimental vibrational spectra and the molecular parameters, applying the FG matrix method of Wilson.
As the approximation of Venkateswarlu and Sundaram for molecules of the type ZXY2 could not stand here, an adapted framework of F matrix elements is proposed. The group of physically acceptable force constants in this series of analogous XY3 and ZXY2 molecules is discussed.
