AbstractStimulated by a complete theoretical investigation of the odd configurations in the Titanium Ispectrum the optical double resonance method has been applied to measure the atomic gJ-values and lifetimes of the excited 3d2 4s 4p z 3F2,3,4-states. Using a Titanium atomic beam in natural isotope composition the following values were deduced from the position and the width of the radiofrequency transition signals:.The experimental results shall be discussed with respect to other experimental and theoretical values.

The hyperfine structure of the level 2 2P1/2 of both 6Li and 7Li has been investigated by means of the optical–radio–frequency double-resonance method. The following values were obtained for the magnetic interaction constants of the two isotopes:[Formula: see text]The gJ value for the 2P1/2 level was found to be −0.6668 ± 0.0020.

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.
