Spectra of Sn2 in argon matrices

Abstract

Absorption, fluorescence, and resonance Raman spectra are reported for the diatomic tin molecule isolated in argon matrices. Fluorescence systems provide information on the location of four excited electronic states, including one only 3000–5000 cm⁻¹ above the ground state. A potential energy diagram is proposed for the low lying states and comparisons are made with matrix‐isolated Pb₂.
