Infrared spectroscopy has been traditionally carried out mainly in absorption. The virtues of
infrared emission spectroscopy have been largely overlooked, but there has been a recent …

Dimers consisting of an alkali metal bound to an alkaline earth metal are of interest from the
perspectives of their bonding characteristics and their potential for being laser cooled to …

Ultracold diatomic molecules find application in quantum studies ranging from controlled
chemistry and precision measurement physics to quantum many-body simulation and …

We report on the formation of mixed alkali–alkaline earth molecules (LiCa) on helium
nanodroplets and present a comprehensive experimental and theoretical study of the …

We present a combined experimental and theoretical study of the RbSr molecule. The
experimental approach is based on the formation of RbSr molecules on helium …

The paper reports on a successful observation of high resolution Fourier transform spectra of
LiCa. The fine structure of the ground state was observed and attributed to effective spin …

We present a thorough theoretical and experimental study of the electronic structure of
RbCa. The mixed alkali–alkaline earth molecule RbCa was formed on superfluid helium …

In this present paper, high-level ab-initio calculations were well performed using multi-
configuration self-consistent field, multi-reference configuration interaction and pseudo …

The 2 2 Σ+ and 4 2 Σ+ excited states of 7 Li 40 Ca have been studied by high resolution
Fourier-transform spectroscopy. The data on the lower state, 2 2 Σ+, were obtained by …

Spectral bands for the B (2) 2 Σ+→ X (1) 2 Σ+ electronic transition in the doubly-polar open-
shell KSr molecule are recorded at moderate resolution using the thermoluminescence …
