摘要

The absorption spectrum of water vapor enriched by deuterium and oxygen-18 is analyzed in the 6000-9200 cm^鈭? region. The spectrum has been recorded at room temperature with a Bruker IFS 120 h Fourier transform spectrometer. More than 14,000 absorption lines were measured in the recorded spectrum. The vibration-rotation assignments were performed on the basis of previously published experimental energies and of variational calculations. Nine water species (H₂¹⁶O, HD¹⁶O, D₂¹⁶O, H₂¹⁸O, HD¹⁸O, D₂¹⁸O, H₂¹⁷O, HD¹⁷O and D₂¹⁷O) were found to contribute to the observed absorption. More than 3600 lines of 19 vibrational bands of D₂¹⁸O and about 4700 lines of 16 bands of HD¹⁸O with J as high as 19 and K_a as high as 11 were assigned. The main part of the HD¹⁸O and D₂¹⁸O lines and all lines of HD¹⁷O and D₂¹⁷O were observed in the laboratory for the first time. The obtained vibration-rotation energy levels are compared with previous experimental studies and the results of variational calculations.
