Prediction of many new optically pumped submillimeter laser lines of deuterated fluoroform on the basis of infrared and submillimeter heterodyne spectroscopy

Over three hundred new submillimeter emission lines were predicted for the ν₅ band of deuterated fluoroform CDF₃ pumped by isotopic CO₂ and N₂O infrared lasers. These lines were calculated by using recently derived molecular constants determined by fitting known infrared, microwave, and submillimeter transitions in CDF₃. The calculated emission lines (estimated accuracy generally within  ± 1 MHz) should be useful to those with specific wavelength requirements. The CDF₃ molecule provides a rich choice of frequencies at approximately 20-GHz intervals extending from about 40 GHz to beyond 1 THz.
