Résumé : We have used continuous-wave cavity ring-down spectroscopy to record the spectrum of H2O[sbnd]Kr in the 2OH excitation range of H2O. 11 sub-bands have been observed for the main krypton isotope, 84 Kr. Their rotational structure (Trot=18 K) is analyzed and the lines fitted together with literature microwave data, with a unitless standard deviation σ=0.86 and 1.32 for ortho and para species, respectively. 4 more sub-bands are observed for the three other isotopes and are also analyzed. The upper state vibrational predissociation lifetime is estimated to 4 ns from observed spectral linewidths.
