“…2 3 In an experiment using pulsed dye-laser excitation, Gornik et al for the first time observed laser-induced Zeeman quantum beats and also measured the lifetime to be 860 ns. 24 In our measurements, a large number of curves were registered for various experimental conditions.…”

“…The modulation of fluorescence in atomic spectroscopy was first demonstrated experimentally by Aleksandrov and by Dodd et al independently in 1964 [2,3]. However, the signal-to-noise ratios they obtained were relatively low, and it was only with the use of pulsed tunable dye laser radiation [5] that QBS started to find numerous applications. Since then, quantum beats have been observed in diatomics [6], triatomics [7], stable [8,9] and unstable polyatomics [10,11], as well as in condensed matter, for example, in semiconductors [12].…”

The depolarization of the rotational angular momentum of electronically excited OH( 2 AE) radicals through collisions with water molecules has been measured using Zeeman quantum beat spectroscopy. The new data have permitted the evaluation of OH(A) state-specific quenching and angular momentum depolarization cross-sections for superthermal OH(A) radicals with mean relative velocities centred around 3500 m s À1 . The quenching cross-sections are compared both with values available in the literature, and with predictions based on a simple harpoon model, and are found to be in good qualitative accord with previous findings. For the lowest rotational levels studied, the depolarization cross-sections (which include contributions from both elastic and inelastic processes in OH(A)) are found to approach s100 Å 2 , only slightly below the high-temperature cross-sections for rotational energy transfer determined elsewhere. The data suggest that under the present conditions rotational energy transfer is accompanied by significant depolarization. The cross-section for the translational moderation of superthermal OH(X) by water is also determined in the present study.

“…The electronic gs factor can be determined by observing Zeeman quantum beats in a well-defined external magnetic field. Zeeman quantum-beats following pulsed laser excitation were first observed by Gornik et al [6]. In our quantum-beat measurements we used ~-excitation in the first excitation step and aexcitation in the D-F transition, a-light was detected in the direction of the magnetic field.…”

Natural radiative lifetimes and Land6 gj factors for several highly excited F states in cesium were measured using time-resolved fluorescence spectroscopy. The F states were excited from the 5 2D5/2 state with a pulse-modulated CW dye laser, and the delayedcoincidence method was employed to record decay curves, which in some experiments exhibited Zeeman quantum beats. A further CW dye laser was used to produce the necessary population in the 5 2D5/2 state. The lifetimes in the sequence 11 16 2/]77/2 follow a n x scaling law with x=2.76 and the Land6 factors agree with the predicted value, 1.143.
