Application of the least squares criterion to the determination of molecular compliance constants

Creator:: Ottinger, Robert Stanley
Abstract:: 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...

I. Infrared spectra of solid solutions in alkali halide crystals [and] Method for obtaining minimal kinematically complete sets of internal coordinates

Creator:: Conant, Donald Robertson
Abstract:: A study was made of the infrared absorption spectrum for cyanate ion in KCl and KBr host lattices containing small amounts of calcium or barium ion. Both pellets and single crystals were scanned during the course of this study. The spectra of the barium or calcium doped crystals contained many...

Infrared investigation of some ferroelectric and related compounds : NH₄NCS, (NH₄)₂SO₄, RbHSO₄, and NH₄HSO₄

Creator:: Oden, L. L. (Laurance L.)
Abstract:: At liquid nitrogen temperature the spectra of sublimed films of NH₄NCS, both as phase I (the usual form stable at room temperature) and phase II (the low temperature form), exhibit detail usually reserved for gases at low pressures. In both phases the symmetry of ammonium ion has degenerated from tetrahedral...

Optical diffraction study of ultrasonic sound velocity in nitrous oxide and ammonia gases

Creator:: Strauch, Joseph George
Abstract:: The velocity of sound in gases was measured, using an ultrasonic wave train as a diffraction grating. The fundamental problems involved in the optical technique are discussed. An apparatus utilizing an objective lens of focal length 1.5 m and aperture f/20 was constructed and used at an ultrasonic frequency close...

Vibrational and reorientational lifetimes in liquids determined by Raman spectroscopy

Creator:: Morgan, Larry G.
Abstract:: 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...
