Self-, Nitrogen-, and Oxygen-Broadening Coefficient Measurements in the ν1 Band of H2O Using a Difference Frequency Generation Spectrometer at 3 μm

An accurate comparison of lineshape models on H2O lines in the spectral region around 3μm

“…Therefore, very strong absorption lines, with intensity as high as 10 À20 cm/mol can be found. The spectral investigation presented in this paper constitutes the extension of a previous work [51] performed by our group on lines in the m 1 band. With respect to that analysis, the present investigation was performed using an implemented version of the previous spectrometer, which is actually endowed with a wider tunability and a laser power increased by a factor '50, which has assured the possibility to perform a very accurate lineshape analysis on the investigated lines.…”

The HITRAN 2008 molecular spectroscopic database

“…These new parameters have been tested for different remote-sensing applications and were found to give improved profiles for atmospheric constituents. The algorithm has been improved for the current release of HITRAN: additional measurements of γ air and δ [18,[33][34][35][36][37][38][39] and γ self [18,[38][39][40][41][42][43][44][45] have been added to the measurement databases. Additional data [46,47] have been added to the theoretical database of γ air , n, and δ.…”

Анализ и аналитическое представление коэффициентов уширения линий водяного пара давлением воздуха, азота, кислорода и углекислого газа для спектрального диапазона 380-26000 cm-=SUP=--1-=/SUP=-

“…Отношения R коэффициентов уширения для переходов из рис. 2 должны группироваться около прямой R ≈ 1.0, однако для экспериментальных данных из [17] и [1,23] R меняется от 0.9 до 3.4. Данные из [17] и [1,23] 011) и (211) данные по уширению воздухом взяты из [7,2] и [9] соответственно, остальные данные -из [13]; при уширении линии азотом данные для (111) взяты из [21], данные для (221), (311), (203) -из [12], для (501) -из [22]; при уширении линии кислородом данные для (111) и (301) взяты из [24] и [6] соответственно.…”
