Atomic and molecular constituents are studied in remote sources using techniques of high-resolution spectroscopy at infrared (IR) wavelengths. Fully resolved spectral line profiles are measured with heterodyne, grating, and Fourier-transform spectrometers, and their intensities and shapes are used to determine abundances, kinetic and excitation temperatures, pressures, velocity shifts, and turbulence. Current research objectives include topics in planetary atmospheres, including the atmospheres of extrasolar planets, comets, and other astrophysical objects, including planetary systems at all stages of formation and evolution. Extensive development of instrumentation is pursued, particularly on IR heterodyne spectrometers and advanced techniques for fully exploiting grating and Fourier-transform spectrometers. Grating-tuned and optically pumped gas lasers are used as IR local oscillators. Current field instrumentation used at Kitt Peak and Mauna Kea includes heterodyne spectrometers and cryogenic (1-28 micron) grating spectrometers, an IR solar vector magnetograph, and submillimeter heterodyne receivers. Observations are also made from observatories, including the Keck Observatory using facility or other instruments. Components suitable for space flight use are being developed.
