Abstract
The spectrum of n{cyrillic}2 18O{cyrillic} has been recorded between 15,000 and 16,000cm-1 by a Fourier transform spectrometer with spectral resolutions of 0.03cm-1 and 0.05cm-1 using high luminance LED light sources and a 60-cm multipath cell with a path length of 1920 and 3480cm. A high signal-to-noise ratio (S/N=10,000) enabled us to register more than 1500 water vapor lines with intensities 1.0×10-27 to 2.2×10-24cm/molecule at 296K. 426 rotational-vibrational levels of the H2 18O molecule were assigned to eleven vibrational states: (014), (033), (052), (113), (132), (151), (212), (231), (311), (330) and (410). 72 Rotational-vibrational levels of the H2 17O molecule were assigned to six vibrational states: (014), (033), (113), (212), (311) and (410). An extended set of H2 18O transitions in the 15,000-16,000cm-1 range was generated using the obtained energy level list and the results of a variational intensity calculation.
