✦ Synopsis

We have reexamined the sequential two-photon absorption of I 2 from the X 1 + g ground state to the lowest D 2 g ( 3 P 2 ) ionpair state using the high vibrational level of the B 3 (0 + u ) state as an intermediate. The double resonance transition to the D 2 g ( 3 P 2 ) state was found to occur through the B 3 (0 + u )-b 2 u coupled state by hyperfine interaction, which permits to mix the different J levels of different electronic states. We elucidated the B 3 (0 + u )-b 2 u coupling schemes in the intermediate states. The double resonance spectra recorded for the D 2 g ( 3 P 2 ) state in the range v = 0-30 were used to determine the absolute energy of the D 2 g ( 3 P 2 ) state. The molecular parameters of the D 2 g ( 3 P 2 ) state obtained in this study are Y 00 = 40 388.783(2),

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
