A new ion-pair state of iodine chloride

A previously-unknown ion-pair state of ICl has been identified and characterized in sequential transitions using polarization-labelling spectroscopy. This state is designated 1( 3 P 1 ), indicating a state of axial electronic angular momentum Ω = 1 correlating diabatically at dissociation with the s...

Description
Summary:A previously-unknown ion-pair state of ICl has been identified and characterized in sequential transitions using polarization-labelling spectroscopy. This state is designated 1( 3 P 1 ), indicating a state of axial electronic angular momentum Ω = 1 correlating diabatically at dissociation with the states I + ( 3 P 1 ) + Cl − ( 1 S 0 ) of the separated ions. The electronic energy and local potential constants for levels with ν = 1-7 are (in cm −1 ) T c  = 45552.805(23), ω c  = 184.854(13), ω c x c  = 0.6737(13), B c  = 0.058898(42), and α = 2.485(93) × 10 −4 , and the equilibrium bond distance is 3.231 Å.
