Far Infrared Spectrum and Ground State Parameters of 12CH3F

Line Intensities in the ν6Band of CH3F at 8.5 μm

“…(5) and the ground state constants from Ref. (6). Gaussian profile and we discarded the perturbed lines.…”

“…band. The spectrum of this band has been analyzed at high A periodic voltage ramp applied to the current controller resolution by Papoušek et al (5,6).…”

Hydrogen-broadening coefficients in the ν5 band of CH3F at room and low temperatures

“…The H 2 -broadenings do not strongly vary with J and K, except the broadenings belonging to transitions with K approaching or equal to J, i.e., R R (3, 3), R R (8, 7), R R (9, 8), R R (9,9), and R R (10,9) which are significantly smaller than the other broadenings. The H 2 -broadenings are, as expected, notably smaller (by a factor $5) than the self-broadenings of CH 3 F [7] but they are [25]. b [14].…”

Self-broadening coefficients in the ν2 and ν5 bands of 12CH3F at 183 and 298K

“…These lineshapes lead to larger collisional widths than those derived from the Voigt profile. It has been equally shown that the broadenings depend strongly on J with a maximum around J $ 13 at room temperature and J $ 11 at 183 K. Calculations of these self-broadening [25]. b Ref.…”
