Characteristic Vibrations of [AuCl4]- (D4h symmetry)

The forms of the normal modes for [AuCl4]- were calculated at the Hartree-Fock level using the SBKJC basis set with effective core potentials.  Listed frequencies are tabulated from work by PJ Hendra (1967, Spectrochimica Acta 23A:2871) and Degen and Rowlands (1991, Spectrochimica Acta 47A:1263).  Frequencies for ν3 and ν5 were not identified in those works, so the ab initio frequency is listed for those vibrations.
