A high resolution interferometer was used to measure the medium- and long-wave infrared absorption spectra of carbon dioxide and nitrous oxide heated to 800K. Modifications were made to the instrument to improve its wavelength accuracy and reliability. In the 4.3-micrometer region, 5 bands of (12)C(16)O(18)O were identified and the corresponding spectral constants were reduced. The constants reproduce the position of the spectra lines to within 0.0005/cm. Absorption spectra of N/sub 2/O and CO/sub 2/ in the 7.8 and 15-micrometer regions, respectively, were recorded and their preliminary analysis has been completed.
