The absorption of the hot bands in the spectra of H2S, SO2, and NO2 at temperatures of 300 – 1000 K

Abstract

In this work the contributions from the hot bands in the total absorption of H2S, SO2, and NO2 were calculated at temperatures of 300 – 1000 K. The high-temperature spectroscopic databases of the authors were applied for calculating the sum absorptions. The reasons of the different contributions from the cold and hot bands in the absorption spectra of the considered gases are discussed.
