The near ultraviolet rotation-vibration spectrum of water

A new ab initio linelist of water vibration-rotation transitions extending up to 26 000 cm(-1) is presented. This linelist is used to analyze the near -ultraviolet portion of the long pathlength water absorption spectrum of Ca rleer [J. Chem. Phys. 111, 2444 (1999)]. A total of 299 of the 568 observed transitions between 21 400 and 25 232 cm(-1) are assigned. These transitio ns belong to eight excited vibrational states: (4,2)(-)1, (7,0)(+)0, (7,0)( -)0, (6,0)(+)2, (6,0)(-)2, (7,0)(-)1, (8,0)(-)0, and (8,0)(-)0, in local mo de notation. Only three of these states have been observed previously. Obse rved and calculated energy levels are presented for these vibrational state s and the band origins are determined.
