Abstract : The 8-15 micron emission spectra of several liquid cyclopentane derivatives have been measured. The samples, all of which have strong absorption bands near 10.6 microns, were excited with a CW CO2 laser operating at a power level of a few watts. Phase-sensitive detection was employed, and both spectral and temporal discrimination were used to distinguish between the thermal and fluorescence components of the radiation emitted by the samples. Early steps have been made toward the development of a theoretical model for calculating the vibration spectra of mono-substituted cyclopentane derivatives. A discussion is given of possible applications of these and other organic liquids to the development of a continuously tunable infrared laser and the generation of ultra-short infrared laser pulses.
