✦ Synopsis

A detailed theoretical study of the spectroscopy of the 1 2 ⌸ u state of Na 2 ϩ is presented, including the determination of Dunham coefficients from recent effective potential calculations of the Na 2 ϩ molecular potential curves. We emphasize the discrepancies existing among several experiments and among several theoretical models available in the literature. The radiative lifetime of the rovibrational levels of the 1 2 ⌸ u state are also computed and are found in agreement within 20% with experiment.

## Abstract We present a comparison between the screened hybrid density functional theory of Heyd, Scuseria, and Enzerhof (HSE06) and high‐resolution photoemission (PES) measurement on a single crystal of UO~2~. Angle‐resolved photoemission data show a slight dispersion in the __f__‐orbital derived

Eleven very weak overtone bands of 14 N 2 16 O have been newly detected by intracavity laser absorption spectroscopy between 10 000 and 12 000 cm -1 . The rotational analysis of three others has been significantly improved. The vibrational assignment of the upper states of the observed transitions h
