Optical Double Resonance

The saturation of level populations induced in a molecule by an intense laser beam may be probed by a second beam at the same or a different frequency. A number of schemes have been based on this principle for simplifying complex spectra or for achieving sub-Doppler resolution. Fluorescence detection provides the sensitivity for studies on free radicals and other transient molecular species. The two beams may be provided by two separate lasers, or by sideband modulation of a single laser. These techniques are reviewed. Emphasis is placed on recent studies of hyperfine structure, of Stark splittings, and of Zeeman splittings.

First Time

Hyperfine structure for several E(0g+)–B(0u+) rovibrational transitions has been measured for the first time. Two single frequency lasers were used to excite E(0g+)(υ*, J*)–B(0u+)(υ′, J′) – X(1Σg+)(υʺ, Jʺ) transitions which result in Doppler-free E(0g+)(υ*, J*)–B(0u+)(υ′, J′) fluorescence excitation spectra. Hyperfine parameters are obtained for E(0g+)υ = 11 (eQq = +483±4 MHz, C = –210±3 kHz) and E(0g+)υ = 8 (eQq = +492.3±2.5 MHz, C = –205±3 kHz). The non-zero C constant is shown to arise from mixing with a nearby 1g state and the eQq constant shows the 3P2(I+) origin of the E(0g+) state.
