✦ Synopsis
The vibration-rotation spectra of both ({ }^{35} \mathrm{Cl}) and ({ }^{37} \mathrm{Cl}) isotopomers of (\mathrm{HOCl}) have been recorded in selected regions between 3900 and (10500 \mathrm{~cm}^{-1}). More than 6000 transitions were assigned to the following overtone and combination bands: (\nu_{1}+\nu_{3}, \nu_{1}+\nu_{2}, \nu_{1}+2 \nu_{2}), and (3 \nu_{1}). A Watsontype Hamiltonian in the (S) reduction and (I^{r}) representation was adopted for the analysis, and the vibration-rotation parameters were derived for the excited states. Their values, together with spectroscopic parameters of the fundamental bands reported in the literature, allowed the calculation of a large set of anharmonicity constants and the vibrational dependence of the rotational constants.

A spectrum of natural OCS has been recorded in the near-infrared region using the laser photoacoustic technique. The source is a titanium-sapphire laser pumped by an Ar ϩ laser. The tunable 1.5 W beam was sent through the photoacoustic cell. This windowless longitudinal resonant cell was designed wi
The near-infrared spectra (3000-10 000 cm -1 ) of 4-chlorophenol-OH and 4-chlorophenol-OD are studied at room temperature in carbon tetrachloride. Some data are also reported for 4-bromophenol-OH and 4-bromophenol-OD. The observed absorptions are assigned to overtones or combinations involving the f
Eleven very weak overtone bands of 14 N 2 16 O have been newly detected by intracavity laser absorption spectroscopy between 10 000 and 12 000 cm -1 . The rotational analysis of three others has been significantly improved. The vibrational assignment of the upper states of the observed transitions h
