Descripción
Atmospheric emission spectra have been measured at an altitude of about
3000 m in the wavelength range from 17.5 to 20 microns. The very high
spectral resolution (up to 0.02 kayser) together with the high
signal-to-noise ratio achieved allow assignment of the observed lines to
CO2, N2O or H2O. Existing spectroscopic molecular data have been
compared with the observations. No serious deviations from the expected
line frequencies are found for CO2 and N2O, but important discrepancies
appear for H2(O-16) transitions occurring at energy levels greater than
2000 kaysers. A few lines due to H2(O-17) and H2(O-18) have been
identified, and deviations from their expected frequencies as large as
0.3 kayser have been measured.
