Absorption of radiation from sodium dimer molecular states correlating to Na(3s)\ensuremath-Na(3s) is investigated theoretically. Vibrational bound and continuum transitions from the singlet X1\ensuremathΣg+ state to the first excited A1\ensuremathΣu+ and B1\ensuremathΠu states and from the triplet a3\ensuremathΣu+ state to the first excited b3\ensuremathΣg+ and c3\ensuremathΠg states are studied quantum-mechanically. Theoretical and experimental data are used to characterize the molecular properties, taking advantage of knowledge recently obtained from ab initio calculations, spectroscopy, and ultracold atom collision studies. The quantum-mechanical calculations are carried out for temperatures in the range from 1000 to 3000 K, and are compared with previous calculations and measurements where available.
