NaLi molecule, laser spectroscopy, electronic states, potential energy curves


We report on our investigation of the excitation spectra of the NaLi molecule in the energy range 31000–33900 cm–1. A polarisation labelling technique is used to ensure rotational resolution of the spectra and to enable unambiguous assignment of the NaLi transitions. A hitherto unknown electronic state of 1Π symmetry is observed. Major molecular constants of the state are determined and its potential curve constructed using the inverted perturbation approach method.
