title: Applications of a tunable CO(2) sideband laser for high-resolution spectroscopic measurements of atmospheric gases.
abstract: A microwave-tuned CO(2) sideband laser system for high-resolution spectroscopic measurements is described. The system is capable of measuring, accurately and reliably, absorption line frequencies, line strengths, self-broadened Lorentz linewidths and line frequency shifts that are due to pressure in the midinfrared. Several transitions of NH(3) are measured and the results are compared with the 1991 edition of the high-resolution transmission molecular absorption (HITRAN) database.
