Abstract:
The vibrational-rotational absorption spectrum of water vapor was recorded and analyzed in the visible region from 19480 to 20500 cm-1. The measurements were carried out at the IFS-125M Fourier spectrometer with a resolution of 0.05 cm-1 at a pressure of 26.3 mbar, a temperature of (24 ± 1) °C at an optical path 24 m long. We used a multipass White cell with a base length of 60 cm. The light-emitting diode was used as the radiation source. The signal-to-noise ratio was about 20000. As a result of the spectrum analysis, a list of more than 420 lines has been formed, which includes line centers and intensity and quantum vibrational-rotational identification. More than 220 vibrational-rotational energy levels of 21 upper vibrational states have been determined.
Keywords:
