Double beam optical techniques which allow direct spectroscopic measurements using both pulsed and cw tunable spin-flip Raman lasers have been developed. The systems provide a high resolution spectrometer (spectral linewidths 0.03 cm-1 pulsed and 0.003 cm-1 cw) in the range 5.3-6µm. Line frequency measurements are accurate to 0.01 cm-1 and intensity measurements to a few percent. Results of molecular spectroscopy provide a comparison of the relative performance of each system. © 1976.
