Fourier-transform spectroscopy and relativistic electronic structure calculation on the c3Σ+ state of KCs
Theoretical study of ThF + in the search for T,P-violation effects: Effective state of a Th atom in ThF + and ThO compounds
We report the results of theoretical investigation of electronic structure of ThF$^+$ cation which is one of the most interesting systems to search for the electron electric dipole moment (eEDM) [H.
Accurate semiempirical potential energy curves for the a3Σ+-state of NaCs, KCs, and RbCs.
A five parameter semiempirical Tang-Toennies type model is used to describe the potential curves of the a3Σ+-state of the heteronuclear polar molecules NaCs, KCs, and RbCs, which show good agreement with dedicated experiments where available.
Theoretical calculation of the excited states of the KCs molecule including the spin-orbit interaction.
The comparison of the present results with those available in the literature shows a very good agreement, while the other results, to the best of the authors' knowledge, are given here for the first time.
The ground electronic state of KCs studied by Fourier transform spectroscopy.
We present here the first analysis of laser induced fluorescence (LIF) of the KCs molecule obtaining highly accurate data and perform a direct potential construction for the X (1)Sigma(+) ground
Theoretical study of the electronic structure of LiCs, NaCs, and KCs molecules
The potential energy has been calculated over a wide range of internuclear distance for 28 lowest molecular states of LiCs, 32 lowest states of NaCs, and 30 lowest states of KCs molecules. This
