Analysis of the hyperfine structure of the Cs2 33Σg+ state

Bichromatic Photoassociation Spectroscopy for the Determination of Rotational Constants of Cs2 0 u + Long-Range State below the 6S1/2 + 6P1/2 Asymptote

“…M. Pichler and co-workers reported the spectroscopic studies of the Cs 2 molecular excited states with the detuning of up to 56 cm −1 from the limits 6S 1/2 + 6P 3/2 [33] and 6S 1/2 + 6P 1/2 [34]. Recently, the spectroscopic detection detuning range has been extended to 70 cm −1 below the Cs 2 6S 1/2 + 6P 3/2 [21] asymptote by our group. Specifically, efforts have been made to further extend the PAS detection range, both to the high-lying molecular vibrational levels within the extremely dense states and to the lower-lying levels that are largely red detuned against the 6S 1/2 + 6P 3/2 [15,18] 6S 1/2 + 6P 1/2 [35] asymptotes.…”

“…However, lines profiles are complicated, influenced by hyperfine interactions, natural linewidth, partial wave dependency, etc. [21,39]. Therefore, we did not try here to estimate the deperturbed line positions.…”

“…In this sense, the PAS is often advantageous in the detection of molecular ro-vibrational energy levels and hyperfine structures over traditional thermo-luminescence spectroscopy or fluorescence spectroscopy techniques [20]. PAS has enabled one to obtain information of molecular structures [21], to determine the long-range behaviour of the potential energy curves and molecular constants [22,23], and to measure the s-wave scattering lengths [4] as well as the time variations of fundamental physical constants [24].…”

Cosine-type Absorbing Optical Potential for the Modeling of Quantum Dynamics with the Fourier Grid and Optimizer Packages

“…We have extensively used earlier versions of the programs described here in our research. Some examples of the applications of our Fourier Grid programs to problems in molecular spectroscopy can be found in, e.g., [2,56,57]. The downloadable package (see Ref.…”
