In order to compare its spectrum with that of other halogenated methanes, the infrared spectrum of chlorofluoromethane has been measured in the gaseous state from 2 to 30 microns. The longest wavelength band was observed at 26 microns. Twenty-five bands have been observed with cells of 5, 60, and 100 centimeters in length and with gas pressures up to 60 centimeters of mercury. Nine of the observed bands have been classified as fundamentals, and the remaining bands are attributed to harmonics and combinations. Several bands in the region from 1.5 to 2.5 microns were measured on a high resolution grating instrument, and it was possible to resolve each of seven bands into a series of lines in this region. These bands are located at 1.657, 1.682, 1.700, 1.755, 2.229, 2.287, and 2.436 microns; the separation of the rotational lines is of the order of 2.3 cmfor these bands.
