The role of Hg 63P0 atoms in mercury photosensitization. IV. Origin of the 4850 Å and 3350 Å bands

Abstract

The continuous emission bands at 4850 Å and 3350 Å, attributed to the decay of electronically excited mercury molecules, have been studied in a flow system in which Hg 6³P₁ atoms were generated in the presence of nitrogen. The mechanism presented to account for the formation and decay of these eximers incorporates the assumption that these bands are derived by spontaneous emission from the A³0_u⁻ and A³1_u states of the mercury molecule respectively. It is proposed that the A³1_u state is the precursor of the A³0_u⁻ state.
