Quantum Beat Spectroscopy and Radiationless Transitions
… single rovibraonic transitions and observed quantum beats in the reversible intersystem crossing of these simple (alpha)-dicarbonyls. We have analyzed the beats by two methods to obtain information concerning the density of interacting states and the average intramolecular coupling energies. …

Quantum beat observations in rubidium vapor
… within the atom that persist longer than 150 ps. Quantum beats due to the interference between the 7S and 5D_{5/2} energy states were observed by a four-wave mixing process. The difference frequency between the 5D–5P_{3/2} and the 5P_{3/2}–5S transitions was also observed for interpulse delays up …

Dynamics of interfering wave packets in rubidium by high resolution quantum beat spectroscopy
High resolution quantum beat spectroscopy has been realized to study atomic wave packet dynamics. Wave packets comprising pairs of low quantum number (n = 5 - 8) electronic states were formed in Rb vapor with ultrafast laser pulses, and their dynamics was observed by an all-optical technique of …

Measurement of Hyperfine Coupling Constants of the 5d²D₃/₂ and 5d²D₅/₂ Levels in Atomic Cesium Using Polarization Quantum Beat Spectroscopy
… experiment, a pump-delayed-probe method based on quantum beat spectroscopy has been used. Cesium atoms are prepared by a short, resonant light pulse ( the pump) in a superposition of excited hyperfine levels ( 5d<sub>2</sub>D<sub>1/2</sub> or 5d<sup>2</sup>D<sub>5/2</sub>) through an electric …

Laser-Induced Fluorescence Studies of Molecular Dynamics
… a molecular beam has been shown to exhibit the quantum beat effect in the time-resolved fluoresence. By the use of a simple, perturbation theory-derived analysis and also a more complicated, simulation-based method, the effective densities of the triplet states involved in the beat phenomena and …

Probing weakly bound long-range Rydberg molecules by quantum beating experiments in rubidium vapor
… with low angular momentum and very low principal quantum numbers (7$s$, 8$s$, 5$d$, 6$d$) are observed in a quantum beating experiment for the first time. The experiments are conducted using parametric four-wave mixing (PFWM) in a pump-probe fashion. Fourier analysis of the time-domain data yields …
