A spectroscopic characterization of the electronic ground state of rhodium monoboride

Abstract

A laser-induced fluorescence electronic spectrum of RhB is reported. It is the first such known example for a metal monoboride. RhB10 and RhB11 species are observed in natural abundance. The molecular ground state has Σ+1 symmetry, an r0 bond length of 0.169nm, and a vibrational frequency of ∼920cm−1.
