Description
In recent years, a growing interest towards open-shell heteronuclear molecules can be noticed. These molecules attract particular attention of physicists involved in experiments at ultracold conditions, because they are known as "doubly polar molecules" having both electric and magnetic permanent dipole moments. Such properties provide a unique possibility for quantum control and simulations.
We report the first spectroscopic investigation of the NaSr molecule. Spectra related to the B(2)$^2\Sigma^+\to$ X(1)$^2\Sigma^+$ transition were observed with partial rotational resolution by thermoluminescence and laser induced fluorescence techniques. Simultaneously, potential energy curves of the lowest electronic states of NaSr and transition dipole moments were calculated using two different theoretical approaches. Comparison with theoretical results allowed to interpret the experimental spectra and deduce the salient molecular constants of the X$(1)^2\Sigma^+$ and B(2)$^2\Sigma^+$ states.
