- Аннотация: The laser production and manipulation of the ultracold molecular ensembles would be greatly facilitated by accurate knowledge of the structure, dynamic, magnetic and electric properties of the electronic states involved (see, e.g., ref. [1]). In spite of the recent progress in the systematic spectroscopic investigation of the promising diatomic species such as alkali metal dimers [2] the reduction of the raw experimental data available for excited electronic states to precise structure (potentials and interaction matrix elements) and radiative (transition dipole moments and Einstein coefficients) parameters is very challenging and still ambiguous procedure. We present here a review of physical models and numerical recipes currently developed for the comprehensive deperturbation treatment of fully mixed [3] and regularly perturbed [4] alkali diatomic states in a wide range of excitation energy and internuclear distance. The crucial role of highly accurate ab initio calculations of the spin-orbit and angular coupling matrix elements [5] in the deperturbation analysis is demonstrated. The homogeneous perturbation effect on nodal structure of the multicomponents wave functions and relevant overlap integrals are discussed [6]. The interpolation and extrapolation properties of the resulting coupled-channel nonadiabatic models are discussed with respect to accuracy required for the adequate reproduction of overall experimental data sets and to reliable predictions of the efficient optical pathways for ultracold molecule production [7].
