Absorption line asymmetry: Speed-dependent effects observed from coherent transients on the 86 GHz line of HC15N in collision with polar and diatomic molecules and with rare gases

The shape of the J = 0→1 rotational line of HC15N at 86 GHz has been recorded in collision with various polar and diatomic molecules and with all rare gases within the 135-300 kelvin temperature range. The coherent transient technique employed, opt

Relaxation parameters for K -components ( K ≤6) of six J → J +1 rotational transitions ( J =6, 10, 17, 22, 31 and 33) of CH 3 35 Cl perturbed by O 2 are measured at room temperature with Voigt, speed-dependent Voigt and Galatry profiles in order

This paper addresses the question of errors in retrievals of vertical profiles of ozone from atmospheric spectra caused by assuming that the absorption lines have pure Voigt line shapes. The case of collisionally isolated transitions (no line mixing)

International audience; The room-temperature nitrogen- and oxygen-broadening coefficients of hydrogen cyanide spectral lines have been measured in the 0.5–3 THz (17–100 cm1) frequency range (purely rotational transitions with 5pJp36) by a continu

N2-, H2-, and He-induced collisional broadening of the J=24←23 transition of HC3N located near 218.3GHz at different temperatures

We report on experimental collisional relaxation of the J = 24 ← 23 line of HC314N, located near 218.3 GHz, induced by nitrogen, hydrogen, and helium. The measurements were carried out at selected temperatures in the 235–350 K range using a video
