Abstract:We measured the rotationally resolved infrared spectra of helium solvated methyl fluoride at 3 μm and 10 μm, wherein lies C‐H and C‐F stretching bands, respectively. The linewidths (FWHM) were found to increase with increasing vibrational energy and range from 0.002 cm‐1 in the v3 band (C‐F stretch) at ~1047 cm‐1, to 0.65 cm‐1 in the v4 band (asymmetric C‐H stretch) at ~2997 cm‐1. In between these two bands we observed the lower and upper components of the Fermi triad bands (ν1/2ν2/2ν5) at ~2859 and ~2961 cm‐1… Show more
