Abstract

Microwave electro-optic modulation of a carbon-dioxide laser beam using CdTe crystals yields a widely tunable infrared source of high spectral purity. This radiation has been used to investigate subDoppler saturation spectra of various molecules like SF₆, C₂H₄, NH₃, OCS or CDF₃. Using two independently tunable electro-optic modulators, it is possible to perform infrared-infrared double resonance with subDoppler resolution. Such a scheme has been used to study the 2v₃ - v₃ hot band transitions of SF₆. The spectrometer design and the experimental details are described. The contribution of these techniques to the knowledge of the molecular parameters are discussed.
