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.
