摘要：
Vibrational overtone transitions of OCS in the near infrared, 10 000-14 000 cm(-1), are observed for the first time by means of the photoacoustic technique. The spectra are analyzed using molecular parameters and Hamiltonions derived far energy levels below 5000 cm(-1). 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. (C) 1997 Academic Press.
