E→BStructured Continuum inI2

Abstract

The recently reported structured continuum of the $E\to B$ transition in ${\mathrm{I}}_2$ is analyzed to determine the $E$-state potential curve and the nature of the electronic transition moment. The minimum of the $E$ curve lies at 41 412 ${\mathrm{cm}}^{-1\mathrm{}}$ with $R_e=3.65\mathrm{}\pm 0.02$ Å, and the dipole transition moment decreases with increasing $R$ beyond ∼ 4 Å.
