Abstract
Within the study of the interaction between A and B states of As2 molecule, a high resolution analysis of 16 absorption bands with 11 ≦ υ ≦ 17 in the A ← X system has been performed. The following constants are proposed for the A state: T00 = 40145.9 cm-1, ωe = 262.7 cm-1, ωe xe = 0.48 cm-1, Be = 0.0797 cm-1, De ≅ 3 X 10-8 cm-1 , αe = 0.00031 cm-1 , re = 2.374 Å. Three new vibronic levels have been discovered in the 42 400 -44 500 cm-1 energy range, either directly or by the perturbations they induce in A levelsKeywords
