Ground and First Excited States of the NaSr Molecule: Experimental and Theoretical Study

Year: 2025
Type: article
Abstract: High Resolution Image Download MS PowerPoint Slide We report the first spectroscopic investigation of the NaSr molecule. Spectra related to the B(2) 2 Σ + → X(1) 2 Σ + 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 by 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 Σ + and B(2) 2 Σ + states. Reliability of the employed theoretical methods was tested.
