✦ Synopsis

We report the analysis of the H1 u ( 3 P 1 ) state of I 2 by optical-optical double resonance. This state lies in the second tier of ion-pair states and its observation was achieved by using the (1 ϩ 2) photoexcitation sequence using the A 3 ⌸ 1u state as an intermediate. The molecular parameters were obtained from data for 0 Յ v Յ 9 and 6 Յ J Յ 135 and used to construct an RKR potential function. We predict the location of unknown h0 u Ϫ ( 3 P 1 ) state in discussing the ⍀-doubling of the H1 u ( 3 P 1 ) state under the pure precession approximation.

Optical-optical double resonance spectroscopy was used to study the 1 g ( 3 P 1 ) ion-pair state of I 2 correlating to I -( 1 S) + I + ( 3 P 1 ) at the dissociation limit. We gained access to the 1 g ( 3 P 1 ) state though the A 3 (1 u ) state in the (1 + 1) photon-excitation scheme. The pump laser

We have analyzed the 1 u ( 1 D) and 2 u ( 1 D) ion-pair states of I 2 by perturbation-facilitated optical-optical double resonance using the B 3 (0 + u ) ∼ c1 g mixing state as an intermediate. The double-resonance spectra exhibited the strong vibrational progression to the 1 u ( 1 D) state in accor
