The temperature dependences of the integrated intensities of the absorption bands of H_2O, H_2S, SO_2, and NO_2

摘要

In this work the temperature dependences of the integrated intensities of the absorption bands of the asymmetric top molecules - H_2O, H_2S, SO_2, and NO_2 were analyzed. A different view of the temperature dependences was shown for cold bands including fundamental ones. For calculating the integrated intensities, the spectral line intensities were used from the known and author's spectroscopic databases. The reasons are discussed which lead to increasing and decreasing the integrated intensities at high temperatures (T>300 K).
