“…We emphasize that table I is by no mean an exhaustive listing of spectroscopic studies on bialkali molecules. For example recent studies have been made on LiNa [73,92,[97][98][99][100], LiK [101], LiCs [102], NaK [103], NaRb [104], NaCs [105], KCs [106][107][108][109][110][111][112], RbCs [113][114][115]. However we show in following sections that a more precise de-TABLE I. References for all the electronic PECs used in the calculations (SOCME ≡ Spin-Orbit Coupling Matrix Elements).…”

In this article we address the general approach for calculating dynamical dipole polarizabilities of small quantum systems, based on a sum-over-states formula involving in principle the entire energy spectrum of the system. We complement this method by a few-parameter model involving a limited number of effective transitions, allowing for a compact and accurate representation of both the isotropic and anisotropic components of the polarizability. We apply the method to the series of ten heteronuclear molecules composed of two of ( 7 Li, 23 Na, 39 K, 87 Rb, 133 Cs) alkali-metal atoms. We rely on both up-to-date spectroscopically-determined potential energy curves for the lowest electronic states, and on our systematic studies of these systems performed during the last decade for higher excited states and for permanent and transition dipole moments. Such a compilation is timely for the continuously growing researches on ultracold polar molecules. Indeed the knowledge of the dynamic dipole polarizabilities is crucial to model the optical response of molecules when trapped in optical lattices, and to determine optimal lattice frequencies ensuring optimal transfer to the absolute ground state of initially weakly-bound molecules. When they exist, we determine the so-called "magic frequencies" where the ac-Stark shift and thus the viewed trap depth, is the same for both weakly-bound and ground-state molecules.

“…Also, note the differing ground and excited state rotational splittings representing the variation in rotational constants between ground and excited vibrational states. We assign these resonances to (4)Ω=1 due to the agreement with theoretical (4)Ω=1 C 6 coefficients [53,54] summarized in Table 3 Transitions are calculated using LEVEL [30] and the B 1 Π PEC [28] and the X 1 Σ + PEC [27]. Unlabeled pair of dips is c-B complex(N=111, J=3,5).…”

“…We approach this discussion by separating the PA resonances observed above and below the Cs 6 2 P 1/2 asymptote. Throughout this chapter, we will follow the notation of Reference [28] and explicitly refer to the vibrational levels predicted by the experimentally deter- and (4)Ω=1, respectively. Also, we note that when describing transitions, we label ground state vibrational levels with double-primes to distinguish them from excited state vibrational levels specified by a single prime.…”

“…Of the 11 resonances which have been previously documented [69], there were three that have only recently been confirmed as belonging to the Ω=2 progression after a claim was made that these PA resonances belonged to the B 1 Π electronic state [28]. To determine the origin of the three PA resonances in question, it is enough to consider the resulting population distribution as the B 1 Π and Ω=2 electronic states couple to the singlet or triplet ground states, respectively.…”
