Rovibrational dynamics of LiCs dimers in strong electric fields

We investigate the effects of a strong electric field on the rovibrational dynamics of LiCs in its 1Σ+ electronic ground state. Using a hybrid computational technique combining discretisation and basis set methods, the rovibrational Schrödinger equation is solved. Results for energy levels and various expectation values are presented. The validity of the previous developed effective and adiabatic rotor approaches is investigated. The electric field-induced hybridization is analyzed up to high rotational excitations and for a large range of magnetic quantum numbers.
