The accurate spectroscopic data of H2 16O in the 1.1 μm region is particularly important for the study of Earth’s atmosphere. The pure water vapor molecular spectra were measured based on direct laser absorption spectroscopy using a narrow line-width external cavity diode laser combined with a high-precision Fabry-Perot etalon. A total of 31 H2 16O transitions were studied for the first time by using speed-dependent Nelkin-Ghatak profile and Hartmann-Tran profile. From an accurate line-shape analysis, we have obtained the line intensities and the self-broadening coefficients, and they are compared with the available reported HITRAN 2016 database and HITRAN 2020 database. Finally, we have obtained information on the influence of Dicke narrowing as well as the correlations between Dicke narrowing and speed dependence and of speed dependent effects. |
