Laboratory measurement of the spectroscopic line parameters of water vapor in the 610-2100 and 3000-4050 cm-1 regions at lower-tropospheric temperatures

High-resolution measurements of the absolute intensities, self- and air-broadened half-widths, self- and air-induced line shifts, and the variation of these parameters with temperature are presented for the infrared lines of water vapor in the 610-2100 and the 3000-4050 cm(-1) spectral regions. In this study spectral lines belonging to the v(1), v(2), v(3), and 2v(2) bands as well as the weak lines of the pure-rotational spectrum have been studied and the dependence of some of the line parameters on the vibrational quantum number has been studied.
