“…Spectroscopy is an interest that remains strong, as evidenced by six of our contributions. Szczepkowski et al present a detailed comparison of ro-vibrational spectra of Sr 2 molecules in their 2 1 Σ u + electronically excited state, finding agreement to ∼0.1 cm –1 accuracy . This is not merely a stringent test of ab initio theory; the Sr 2 molecule is a significant player in precision searches for exotic physics.…”
