✦ Synopsis

The three lowest vibrational bands 1 ← 0, 2 ← 1 and 3 ← 2 of 20 NeH + in the 1 + ground electronic state are recorded from IR emission of a positive column discharge with a Fourier transform Bruker 120 spectrometer between 1800 and 3000 cm -1 . Accurate integrated intensities have been measured for 75 vibration rotation transitions. The diagonalisation procedure first developed by T. Tanaka et al. [J. Mol. Struct. 153, 413 (1997)] was applied for the determination of the transition dipole moment of NeH + . With the reported theoretical value of the permanent dipole moment taken as 3.004 D, the vibrational transition moment µ 1-0 is determined to be 0.314 ± 0.026D, with one standard deviation.

The pure rotational spectra of five isotopic species of thiophosphoryl chloride, SPCl 3 , have been examined in detail in the frequency range 26 -110 GHz. This study has shown that the frequencies previously reported for the rotational transitions of three symmetric-top species of SPCl 3 in the grou

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 sup

A set of 26 new measurements have been recorded by a Doppler-free double-resonance technique, with a relative accuracy of about 10(-8). These data are combined to previous FTIR measurements to refine the molecular constants of 12CH3I. All the available literature data have been revisited, a few assi
