The ratio of the absolute infrared intensity, A₃/A₂, for the
parallel mode (2336 cm⁻¹) and the perpendicular mode (658 cm⁻¹)
of a nonpolar solute molecule, carbon dioxide, has been determined
in a nonpolar solvent, Nujol. The solution ratio (5.0) which has
been extrapolated to zero concentration is less than the...
The development of a least squares model for the
determination of compliance constants from various combinations
of vibration frequency, mean square amplitudes
of vibration and centrifugal distortion data is discussed.
The resultant model is applied to frequency and mean square
amplitude data for NO₂ and N₂O₄ and to frequency and...
Theoretical studies and experimental results are presented for the rotational motion of molecule's in crystalline solids. The group theory is solved for molecules of any symmetry matrix isolated at a site in a crystal field of any symmetry. As the potential terrier to rotation of the molecule relative to the...
Studies of anisotropic and isotropic Raman line shape yield information about the rotational motion (rotational correlation function) and non-reorientational (vibrational) lifetimes. The rotational motion of carbon disulfide has been studied previously by the techniques of Raman spectroscopy (6, 43), Rayleigh scattering (43, 46) and direct measurement (47). This work was...
