Calculation of the intensities of vibrational hydrogen sulfide transitions for remote sensing of high-temperature media

Integral intensities of vibrational bands are calculated for hydrogen sulfide (H 2 S) taking into account the Fermi and Darling–Dennison resonances. Components of the dipole moment function in normal coordinates and parameters of the effective vibrational Hamiltonian borrowed from the literature are...

Summary:Integral intensities of vibrational bands are calculated for hydrogen sulfide (H 2 S) taking into account the Fermi and Darling–Dennison resonances. Components of the dipole moment function in normal coordinates and parameters of the effective vibrational Hamiltonian borrowed from the literature are used as initial data. From several sets of the dipole moment function parameters, we have chosen the set of the parameters computations with which provide the closest agreement with the experimental integral intensities of the H 2 S bands. As a result, predictive computations of the vibrational band intensities (ΣΔυ i  = 2) are carried out at temperatures in the range 600–1500 K.
