Sažetak
Recently heteronuclear molecules have been detected at ultra cold conditions and some very interesting laser spectroscopy has been carried out for those molecules under conditions of magneto-optical traps. Heavy alkali heteronuclear molecules became very attractive recently and their observation on helium clusters is desirable, since triplet states are most prominent features in nano-cryostat conditions. Potential curves for heteronuclear molecules are becoming better known in both cases with and without spin-orbit interaction taken into account. Singlet transitions are better known than triplet transitions in usual laser spectroscopy. However, at ultra low temperatures triplet states become more accessible and thus analysis reveal the structure of the potential curves for triplet manifold. Optical transitions within triplet states, sometimes called diffuse bands, may be used for two-photon resonance ionization scheme. We shall discuss absorption spectra at high density alkali vapor mixture at thermal conditions, in the case of excitations from the He droplets, and under ultra cold conditions. Recent observations may contribute to the final interpretation of heteronuclear diffuse bands in the broad spectral region.
