Vibration Rotation

Vibrational absorption bands of methyl isocyanide and its d 3 -derivative have been measured with higher resolution than previously, and the rotational structure of some bands has been analysed. The band origins have been determined for some parallel bands and molecular constants have been derived. A more detailed examination of the fundamental bands of the degenerate vibrations of both molecules has led to a determination of A" and of the Coriolis coupling coefficients for v 5 , v 6 , v 7 and v 8 . Several perturbations arising from Fermi or Coriolis interactions have been explained.

Methods for determining the true widths of lines in simple vibration-rotation bands have been considered, and a procedure has been devised for studying the effect of added gases upon the line widths in the fundamental vibration bands of deuterium chloride and carbon monoxide

Primary Cosmic Rays

Primary cosmic rays passing through the solar system carry with them valuable information about solar and astrophysical phenomena in the form of intensity and spectral variations. In order that this information be efficiently extracted from observations of the directional cosmic-ray flux at the surface of the Earth, it is essential to have accurate information available to enable the relating of the observed secondary cosmic-ray directions of motion and intensity to those outside the range of the disturbing terrestrial influences.

The microwave rotational spectrum of the hydrogen-bonded heterodimer CH 3 CN • • • HF has been identified and shown to be characteristic of a symmetric top. A detailed analysis of several rotational transitions for a variety of isotopic species gives the spectroscopic constants summarized in the following table: Rotational constants/MHz, vibration-rotation constants/MHz and vibrational separations/cm -1 of CH 3 CN • • • HF

Normal Coordinate Calculation

The infrared spectra of 1-chloropropyne and 1-chloropropyne-d3 have been investigated in the vapor state, in solution, and, in part, in the liquid over the spectral region 3 to 35 μ. Intensities of the infrared bands have been measured from the spectra of the solutions. The Raman spectra of the compounds in the liquid state, together with standard intensities and depolarization ratios of the Raman bands, were obtained. A complete assignment, based on a normal-coordinate calculation of the fundamentals, has been made. Coriolis coupling coefficients of three of the perpendicular-type fundamentals of CH3≡CCl were determined and those of the other two shown to be near unity. Two coupling coefficients for CD3C≡CCl were obtained. The potential function and isotope effects on Raman intensity and Raman displacement of the CCl stretching vibration are discussed.
