title: Laser Spectroscopy of Vibration-Rotation Lines in the 3 <-- 0, 5 <-- 0, and 6 <-- 0 Overtones of HBr
abstract: The Doppler-limited vibration-rotation absorption spectrum of HBr in the near infrared wavelength region was measured using a GaAs semiconductor laser and a ring-type titanium sapphire laser. About 100 lines in the v = 3 <-- 0, 5 <-- 0, and 6 <-- 0 bands were assigned and 16 Dunham coefficients Y10-Y50, Y01-Y41, Y02-Y22, Y03-Y13, and Y04 for H79Br and H81Br species were determined by a global least-squares fit using the v = 0, v = 1 --> 0, and v = 2 --> 1 lines by V. Braun and P. F. Bernath (J. Mol. Spectrosc. 167, 282-287, 1994), the v = 7 <-- 0 lines by P. Bernage and P. Niay (C. R. Acad. Sci. Paris Ser. B 282, 243-245, 1976), and the v = 3 <-- 0, v = 5 <-- 0, and v = 6 <-- 0 lines by this work. Copyright 1997Academic Press
