    Notes: Abstract Heterodyne frequency measurements have been made on the 12°0-00°0 band of carbonyl sulfide in the wavenumber range from 1866 to 1915 cm−1. Frequency measurement techniques reported earlier are used to measure the OCS absorption lines by means of a tunable diode laser, a CO laser local oscillator, and two CO2 lasers used as secondary frequency standards. A table of calculated absorption frequencies is given for OCS from 1866 to 1919 cm−1.

    Notes: Abstract Heterodyne frequency measurements are reported for absorption transitions of N2O in the frequency range from 1257 to 1335 cm−1. The measurements use a CO laser as a transfer oscillator whose frequency is measured directly against combinations of frequencies of two stabilized CO2 lasers whose frequencies are well known. A tunable diode laser is locked to the N2O absorption feature and the frequency difference is measured between the diode laser and the CO laser. Thev 3 fundamental bands of the15N14N16O and14N15N16O isotopes are reported. Measurements are also given for the 0002–0001, 0201–0200, and 0221–0220 vibrational transitions of N2O. A table of frequencies is given for the 0002–0000 band near 2560 cm−1 based on these and earlier measurements.
