In the present paper we propose to measure the index of refraction for diatomic sodium molecules traveling through a cold helium gas. Theoretical calculations of the index of refraction for this system are presented as a function of the molecule velo

An extended geminal model has been applied to determine the interatomic potential for the X 1 Σ + g state of Be 2 . By adopting a (23s, 10p, 8d, 6f, 3g, 2h) uncontracted Gaussian-type basis, the following spectroscopic parameters are obtained: R e =

Vibrationally resolved N2+ (B–X) (1–2) and (0–1) emission bands were recorded after photoexcitation of N2 in the 20–46 eV energy range. The branching ratio between these transitions reveals strong non-Franck–Condon effects. Ab initio calcul
