Mean amplitudes of vibration: Pyramidal XYZ2 molecules

  • K. Venkateswarlu
  • K. V. Rajalakshmi


The theory of mean square amplitude of vibration using the symmetry co-ordinates has been applied to the pyramidal XYZ2 molecular model. The elements of the mean square amplitude matrices and the mean amplitude quantities at 300° K. for thionyl halides have been reported.
