- Аннотация: We have carried out the direct deperturbation analysis of about 780 rovibronic term values of the strongly spin-orbit (SO) coupled A1Σ+ and b3Π states of the 7Li133Cs molecule recorded by polari- zation labelling spectroscopy technique. The explicit A1Σ+∼b3Π_Ω=0,1,2 coupled-channels treatment allowed us to reproduce 95% experimental term values with a standard deviation of 0.05 cm−1 which is close to the accuracy of the present experiment. The initial potential energy curves (PECs) of the mutually perturbed states and SO matrix elements were ab initio evaluated in the basis of the spin-averaged wave functions. The empirically refined PECs and SO functions, along with the theoretical transition dipole moments, were used to predict energy and radiative properties of the A ∼ b complex for low J levels of both 7Li133Cs and 6Li133Cs isotopologues. The reasonable candidates for the stimulated Raman transitions between initial Feshbach resonance states, the mixed levels of the A ∼ b complex, and absolute ground X1Σ+ (v = 0 and J = 0) state were identified.
