12ch2f2 And 13ch2f2far-infrared Lasers: New Lines And Frequency Measurements

We report here the discovery of 13 new far-infrared laser lines from 12CH2F2 and seven new lines from 13CH2F2. Most of the new lines were pumped by high-J lines of the 9R branch of a cw-CO2 laser. Wavelengths range from 97.6 to 616.18 μm. Frequency, pump offset, relative polarization, and relative intensity were measured for most of the new lines.181223012306Douglas, N.G., Millimeter and Submillimeter Wavelength Lasers (1989) Springer Series in Optical Sciences, , Springer-VerlagDeroche, J.C., Benichou, E.K., Guelachvili, G., Assignments of submillimeter emissions in difluoromethane pumped by 12C16O2 and 12C18O2 lasers (1986) Int.
