Abstract
Two new emission systems of violet degraded bands near 4000 Å were recorded from microwave discharges through mixtures of beryllium halide vapors with flowing argon and krypton at pressures ~ 200 Torr. The spectra are assigned as the A2Π–X2Σ+ systems of the hitherto unknown BeAr+ and BeKr+ molecules. Molecular constants are reported, and the large binding energies are discussed in terms of a predominant ion-induced dipole interaction.Keywords
