      More Details Abstract Fulltext PDF

      A complete vibrational analysis of the methyl ammonium ion CH3NH3+, and of CD3NH3+, CH3ND3+ and CD3ND3+ is described in this paper. A General valence Force Field has been computed for these ions, belonging to C sysmmetry, using the fundamental frequencies obtained from the infrared spectra. The mean square amplitudes and shrinkage constants and Coriolis coupling constants have also been calculated for the first time and presented here.

      More Details Abstract Fulltext PDF

      A complete vibrational analysis of PSF3 and NSF3 molecules is described in this paper. Urey-Bradley and General valence Force Fields have been computed for these molecules, belonging toC3 symmetry using the fundamental frequencies obtained from infrared spectra. The mean square amplitudes, Coriolis coupling coefficients and centrifugal distortion constants have also been calculated and presented here.
