Abstract

The new calculation approach of water vapor rotational energy levels using symmetric top model for K_a>=J/2>>1 has proposed. The rotational spectroscopic parameters of the Pade-approximation for ground vibrational state of H₂O molecule in the frame of this model was obtained. The absorption coefficient of water vapor in a spectral range 850-920 cm^-1 was calculated for 1000 - 10000 K temperatures.
