Paper Abstract

A new folded variant of optical-optical double resonance has been developed for the detailed characterization of polyatomic species that contain chemically significant quantities of vibrational excitation. Based upon a novel implementation of phase-conjugate degenerate four- wave mixing (DFWM) spectroscopy, this technique provides a quantum state-specific probe of molecular topography and dynamics that offers substantial advantages over more conventional methods. Despite the third-order nonlinearity inherent to the DFWM process, the tremendous resonant enhancement that accompanies this Doppler-free interaction permits facile detection of double resonance signals even under the rarified conditions present in a molecular beam environment.
