Study of Water Absorption Lines in the Near Infrared

Abstract

Progress has been made in the following area: (1) Development of a tunable 5 micrometer spin-flip Raman laser and application to precision spectroscopy of H2O; (2) Studies of wings of water vapor lines; (3) Other spectroscopic applications of the spin-flip Raman laser; (4) Development of a tunable 5 micrometer pulsed laser; (5) Spectroscopy of D2O using an acoustical modulator for frequency tuning; (6) Velocity dependence of collision processes in NH3; (7) Theoretical formulation of absorption far from line center - collision induced absorption in rare gas mixture.
