Terahertz spectroscopy applied to the measurement of strengths and self-broadening coefficients for high-J lines of OCS

Autor: Gaël Mouret, Francis Hindle, S. Matton, Arnaud Cuisset, F. Rohart, Damien Bigourd, Robin Bocquet

Publikováno v: Journal of Molecular Spectroscopy. 239:182-189

A spectrometer operating in the 100–2000 GHz range and allowing for absolute line strength measurements has been developed. The continuous wave terahertz radiation is generated by mixing two Ti:Sapphire laser beams in a vertically integrated low te

K-dependence and temperature dependence of N2- and O2-broadening coefficients for the J=14–13 transition of methyl chloride CH335Cl

Autor: Jean-Pierre Bouanich, Jean-Marcel Colmont, Georges Wlodarczak, F. Rohart

Publikováno v: Journal of Molecular Structure. :268-276

Extensive experiments on the K=5 component of the J=14–13 rotational transition of CH335Cl, located near 372 GHz, were performed at different temperatures in the range 235–350 K. They allow the determination of the N2- and O2-broadening coefficie

N2- and O2-broadening coefficients and profiles for millimeter lines of 14N2O

Autor: F. Rohart, Georges Wlodarczak, Jean-Marcel Colmont, Jean-Pierre Bouanich

Publikováno v: Journal of Molecular Spectroscopy. 222:159-171

For the purpose of atmospheric applications, we have measured N 2 - and O 2 -induced broadenings and shapes of rotational lines of N 2 O in the 235–350 K temperature range, precisely the J =8←7, J =22←21, and J =23←22 lines, located near 201,

Infrared HCN Lineshapes as a Test of Galatry and Speed-Dependent Voigt Profiles

Autor: F. Rohart, B. Lemoine, J.-F. D'Eu

Publikováno v: Journal of Molecular Spectroscopy. 212:96-110

Absorption lineshapes of the ν2 infrared band of HCN in collision with He, Ne, Ar, Kr, Xe, N2, HCN, and CH3Br have been considered. Observed lineshapes differ significantly from the usual Voigt profile and are characteristic of line narrowing proces
