The observation of some new bands assigned to the Na3 X–A system has allowed a rather complete theoretical treatment of the A electronic state. It exhibits large quadratic Jahn–Teller interaction giving rise for the lower levels to a localization in a hindered pseudorotation well. The band positions and intensities are in agreement with the values Es=1847 cm−1 and Eloc=196 cm−1, respectively for the stabilization and pseudorotation barrier energies.
