TRANSITION FREQUENCIES AND ABSOLUTE STRENGTHS OF (H2O)-O-17 AND (H2O)-O-18 IN THE 6.2-MU-M REGION

High-resolution spectra of oxygen-enriched samples of water vapor were recorded with a Fourier-transform spectrometer covering transitions in the (010)-(000) bands. The measured line frequencies were used along with measurements taken from studies at microwave and far-infrared frequencies to obtain rotational energy levels in the (000) and (010) states of (H2O)-O-17 and (H2O)-O-18. Measurements of the line strengths were fitted to a model in which as many as 18 transition moment parameters were determined. The results produced computed line-strength values that are in excellent agreement with the 623 (H2O)-O-17 experimental transition strengths and 696 (H2O)-O-18 values. These results provide a more accurate representation of the line positions and strengths for the (010)-(000) bands of (H2O)-O-17 and (H2O)-O-18 those previously available.
