The vibration-rotation emission spectrum of free BeH2

The gaseous BeH2 molecule has been synthesized by means of an electrical discharge inside a high-temperature furnace and identified with infrared emission spectroscopy. The antisymmetric stretching mode nu3 has been detected near 2179 reciprocal centimeters. The BeH2 molecule has a linear, symmetric...

Description
Summary:The gaseous BeH2 molecule has been synthesized by means of an electrical discharge inside a high-temperature furnace and identified with infrared emission spectroscopy. The antisymmetric stretching mode nu3 has been detected near 2179 reciprocal centimeters. The BeH2 molecule has a linear, symmetric structure with an r0 BeH bond length of 1.333761(2) angstroms.
