Nonadiabatic Effects in (1 similar to 2)(1)Pi-X-1 Sigma(+) Rovibronic Transitions of KRb Molecules

摘要

Numerical simulation of the effect of intramolecular electrostatic interactions on redistribution of relative intensities in the vibrational structure of (1 similar to 2)I-1 -(XI)-I-1 (+) pound rotationally resolved transitions of the KRb molecule is performed within the precision nonadiabatic model of coupled vibrational channels. It is established that mutual perturbation of electronically excited states modifies in a nontrivial way a nodal structure of nonadiabatic wavefunction of the (1 similar to 2)I-1 complex, which is possible to use for rising efficiency of twostep laser synthesis and stabilization of ultracold ensembles of KRb molecules in the ground electronic state.
