Calculation of the normal vibrations and conformations of the (CH3O)2P(S)SH molecule


  1. 1.

    Frequencies and normal vibration forms have been calculated for various models of the (CH3O)2P(S)SH molecule, and the more probable conformations of this molecule were discussed.

  2. 2.

    Theoretical analysis shows that the band splitting observed in the IR spectra of such compounds can be due to rotational isomerism.
