The gas phase spectrum of N2H2 has been investigated in the region of 7.6 μm at a resolution of about 0.06cm−1. Two bands have been identified; one, near 1288 cm−1, is a type C band and must correspond to ν4 (the hitherto unidentified Au torsional mode), and the other, near 1317 cm−1, is a type A–B hybrid and corresponds to ν6 (the Bu bending mode). Analysis of the spectrum is complicated by the simultaneous presence of strong A-type and B-type Coriolis interactions which couple the observed levels.

AbstractVarious refined potentials describing the intra- and inter-molecular force fields of water molecules arc used to calculate the properties of the gas-phase water dimer. The intra-molecular parts have been taken from spectroscopic or quantum-chemical sources. The minimum energy structure was found iteratively using the first derivatives of the potential; the force-constant matrix was constructed by numerical difierentation. A quite close agreement between the Bopp-Jancso-Heinzinger and the Matsuoka-Clementi-Yoshimine-Lie potentials is found. The treatment is applied to seven observed water-dimer isotopomeric isomerizations

Twist Mode

Infrared and Raman spectra have been measured for spiropentane-H8. Raman spectra for the liquid have enabled the b1 species ring twist to be assigned. Previous assignments of this mode were based on calorimetric data and on the assignment of a band in the infrared spectrum to a combination band involving the ring twist mode. Infrared spectra of low temperature crystalline films have provided sufficient information that, when taken with the Raman data and gas phase infrared spectra, we have assignments for all of the fundamental modes.
