title: Diode laser-CO(2) laser heterodyne spectrometer: measurement of 2sQ(1,1) in 2nu(2) - nu(2) of NH(3).
abstract: A carbon dioxide laser has been coupled with a tunable diode laser spectrometer for heterodyne calibration of molecular spectra. The output of the diode laser is measured to be 10-15 MHz wide and is stable to within +/-2 MHz. The frequency of the 2(s)Q(1,1) transition in the 2nu(2) - nu(2) band of ammonia is measured to be 949.44746(24) cm(-1).
