Vibrational Analysis of the A³Π₀−X¹Σ⁺ and B³Π₁−X¹Σ⁺ Subsystems of the GaBr Molecule

Abstract

The emission band spectrum of gallium monobromide has been excited in a dc hollow cathode discharge. bands of the ³Π_0,1−X¹Σ⁺ system, lying in the range from 340 to 370 nm have been recorded at high resolution and measured. The previous vibrational analysis has been revised and corrected. New vibrational assignment has been proposed and improved vibrational constants of the upper and lower electronic states have been determined.

Key Words:

• vibrational constants
• gallium monobromide
• emission spectra
