title: Laser Photoacoustic Detection of High Overtone Transitions of ClCN in the Near Infrared.
abstract: A titanium-sapphire laser associated with a photoacoustic spectrometer was used to record the spectrum of ClCN between 10 300 and 13 000 cm(-1). The 01(1)5-01(1)0, 00(0)5-00(0)0, and 00(0)6-00(0)0 vibrational bands have been detected for both (35)Cl(12)C(14)N and (37)Cl(12)C(14)N molecules. The rotational structure of the 00(0)5-00(0)0 band has been observed at high resolution and fully analyzed for the main isotopomer (35)Cl(12)C(14)N. Rotational constants of the upper state of this transition have been determined. The anharmonic vibrational constants of the nu(3) mode were evaluated up to the fourth order from the new band origins and bandhead positions. Copyright 1999 Academic Press.
