Cavity-ring-down spectroscopy on water vapor in the range 555-604 nm

The method of pulsed cavity-ring-down spectroscopy was employed to record t he water vapor absorption spectrum in the wavelength range 555-604 nm. The spectrum consists of 1830 lines, calibrated against the iodine standard wit h an accuracy of 0.01 cm(-1); 800 of these lines are not obtained in the HI TRAN 96 database, while 243 are not included in the newly recorded Fourier transform spectrum of the Reims group. Of the set of hitherto unobserved li nes, 111 could be given an assignment in terms of rovibrational quantum num bers from a comparison with first principles calculations, (C) 2001 Academi c Press.
