Abstract

Gaseous strontium dibromide has a quasilinear molecular structure according to a joint electron diffraction/vibrational mode analysis in agreement with recent ab initio studies. The thermal-average (rg) and equilibrium (re) bond lengths are 2.783±0.006 and 2.738±0.013 Å, respectively. The estimated vibrational frequencies ν1, ν2, and ν3 are, respectively, 165 ± 21, 31 ± 10, and 283 ± 36 cm-1.
