TLDR
In this paper, a 6s2(1S 0)6s 2 6s 6p(1P 1 )(1Σ+g) → 6s 2(1 S 0) 6s6p (1P1)(1 Σ+u) transition was observed for group IIA metal dimers.Abstract:
Matrix isolated Yb vapor spectra show absorptions due to atoms, dimers, and higher aggregates. The atomic spectrum reveals strong 395 and 344 nm bands and very sharp weaker 267 and 255 nm absorptions in solid argon. The spectrum of Yb2 shows extensive vibrational stucture around 550 nm both in Ar and Kr matrices with a spacing of 48 cm−1. This absorption is assigned to a 6s2(1S0)6s2(1S0)(1Σ+g) →6s2(1S0)6s6p(1P1)(1Σ+u) transition similar to the one observed for group IIA metal dimers. Higher aggregate spectra overlap with the 550 nm dimer and weak atomic band.read more

Actinide gas-phase chemistry : reactions of an+ and ano+ an = th, u, np, pu, am with nitriles and butylamine
TL;DR: In this article, the role of the coordinating N:1 site on actinide ion−molecule interactions was assessed and the results for the nitriles were generally reminiscent of those for reactions with alkenes and the inert character of Pu+ and Am+ with regard to dehydrogenation.

Absorption spectra of matrix‐isolated alkaline earth metal diatomic molecules
Abstract: Mg, Ca, and Sr atoms were codeposited with argon and krypton at 10 K for optical absorption investigation of the van der Waals diatomic molecules. Very strong and weak structured absorptions were observed for Mg2 at 367 and 444 nm, respectively. An unstructured 507 nm and a strong structured 648 nm absorption were found for Ca2, and a strong structured 710 nm absorption was observed for Sr2. Intermediate absorptions with intermediate spacings were observed for CaMg, SrMg, and SrCa in mixed‐metal experiments. The strong absorptions are assigned to 1Σ+u(1S+1P) ←1Σ+g(1S+1S) transitions.
