Prediction of new optically pumped submillimeter-wave laser lines in deuterated fluoroform

Over 300 new submillimeter-wave laser emission lines are predicted for the ν5band of deuterated fluoroform (CDF3) when isotopic CO2and N2O infrared pump lasers are used. These lines are calculated by using recently derived molecular constants that were determined by fitting known infrared, microwave, and submillimeter-wave transitions in CDF3. The calculated emissions (estimated accuracy generally within ± 1 MHz) should be useful to those with specific wavelength requirements. The molecule provides a rich choice of frequencies at approximately 20 GHz intervals extending from about 40 GHz to beyond 1 THz. This approach eliminates much of the usual trial-and-error technique of finding new submillimeter-wave emission lines.
