Paper Abstract

Electronic emission bands of In2 are generated (a) in a microwave discharge in a quartz cell containing the metal plus a low pressure of Ar or Ne and (b) by radiative combination of In atoms excited to the 6SS1fl state with In atoms in the ground (52P1) state. In (a) a band progression to high energies was observed commencing at 25 730 cm1 which can be fit by moelcular constants of ue 105.3 cm1, COXe 26.2 cm1, and De 212 cm1. In (b) strong, unresolved, overlaped band features were observed in the 380 nm wavelength region (25 500 cm1 to 27 000 cm ) and a weaker, broad feature at 375 cm1 (28 300 cm1 to 30 000 cm1).
