Successful Observation

The failure to observe a microwave spectrum of dichloroketene prepared in a low temperature flow system is contrasted with the successful observation of its Fourier Transform infrared spectrum under the same conditions. It is concluded that the lack of a microwave spectrum is a result of a near-zero dipole moment for dichloroketene.

Oxygen Concentrations

Low temperature Fourier transform infrared measurements at 20 K on some wafers containing substitutional atomic carbon and oxygen are presented. Spectral subtraction techniques at 20 K indicate an increase of approximately 5 times in sensitivity compared to the room temperature evaluation of the carbon and oxygen concentrations.

Unitary Equivalence

The high-resolution Fourier transform infrared spectrum of nitrogen trifluoride NF3has been studied in the v1+ v4perpendicular band region around 1523 cm−1. All experimental data have been refined applying various reduction forms of the effective rovibrational Hamiltonian developed for an isolated degenerate state of a symmetric top molecule. The v1= v4= 1 excited state of the14NF3oblate molecule was treated with models taking into account ℓ- andk-type intravibrational resonances. Parameters up to sixth order have been accurately determined and the unitary equivalence of the derived parameter sets in different reductions was demonstrated.
