摘要

High-resolution water vapor absorption spectra have been measured at room temperature in the 8800-11,600 cm^鈭? spectral region. They were obtained using the mobile BRUKER IFS 120M Fourier transform spectrometer (FTS) from ULB-SCQP coupled to the 50 m base long multiple reflection White type cell in GSMA laboratory. The absorption path was 600 m and different H₂O/HDO/D₂O mixtures were used. Measurements of line positions, intensities and self-broadening coefficients were performed for the HD¹⁶O isotopologue. 6464 rovibrational assignment of the observed lines was made on the basis of global variational predictions and allowed the identification of new energy levels. 3谓₃, 2谓₁+谓₃, 3谓₁+谓₂, 谓₁+2谓₃ and 2谓₂+2谓₃ are the five strongest bands. The present paper provides a complementary data set on water vapor for atmospheric and astrophysical applications.
