✦ Synopsis

The millimeter-and submillimeter-wave spectra of CuF and AgF in the X 1 + states were observed by employing a sourcemodulated microwave spectrometer. The CuF and AgF molecules were generated in a free space cell by a dc glow discharge in CF 4 and Ar. The copper and silver atoms were respectively supplied by sputtering from a copper cathode and silver sheets placed on the inner surface of a stainless-steel cathode. Rotational transitions of 63 CuF, 65 CuF, 107 AgF, and 109 AgF in highly excited and ground vibrational states were measured in the region between 200 and 400 GHz. The transition frequencies were analyzed by a least-squares method using a combined-isotopomer Dunham-type term energy expression.

The coherent Raman spectra of electrically discharged 14 N 2 and 15 N 2 were analysed using the deformationally self-consistent procedure for the treatment of spectral data. By making use of eight independent unconstrained parameters, 356 measured spectral lines were reproduced with s = 0.0023 cm -1
