Abstract:

Intensities of water vapor absorption lines of the hot bands in the region from 1500 to 2100 cm^-1 are estimated to update the spectral information needed when studying the kinetics of water vapor vibrational states in the middle atmosphere and non-equilibrium atmospheric emissions. Hot lines in this spectral region are due to transitions from the first triad of vibrational states to the second triad of the excited vibrational states (110, 011, 030). Computation of the line centers is based on the method of effective Hamiltonian and G-functions method. The parameters of the effective dipole moment are estimated based on the derivatives of H₂O dipole moment function we have constructed.
