✦ Synopsis

Vibrational overtone transitions of OCS in the near infrared, 10 000-14 000 cm 01 , are observed for the first time by means of the photoacoustic technique. The spectra are analyzed using molecular parameters and Hamiltonions derived for energy levels below 5000 cm 01 . It is demonstrated that the molecular parameters of OCS for the low vibrational states can be extended to higher vibrational states within experimental accuracy. A total of 14 transitions in three polyad groups were assigned. Strong perturbations were observed in these highly excited states of OCS.

The near-infrared electronic transition of CuCl, occurring in the region of 745 nm, was recorded using intracavity laser absorption spectroscopy. The (0, 0), (1, 1), and (2, 2) vibronic bands were analyzed, and from this the molecular constants for the two electronic states were derived. Originally
