“…Furthermore, by combining our data with the data clearly and unambiguously (2). data of Ishiwata et al (9), we present Dunham coefficients Multiphoton absorption techniques using tunable laser for the state valid over the vibrational range u, = 0-74. beams have recently been introduced to clarify the assignment of the UV emission spectrum of molecular iodine. More than half of the 2 0 ion-pair states correlating with I-(IS) + I'(~P, 'D, IS) have been spectroscopically identified (3)(4)(5)(6)(7)(8).…”

“…More than half of the 2 0 ion-pair states correlating with I-(IS) + I'(~P, 'D, IS) have been spectroscopically identified (3)(4)(5)(6)(7)(8). Ishiwata et al (9) reported an optical-optical double resonance (OODR) study of the F'o: state over the vibrational range v' = 0-38. Lehmann, Smolarek, and Goodman (10) observed under low resolution, using a single laser beam, seven multiphoton ionization (MPI) lines in the 19 500 cm-I region of the spectrum, which they did not analyse.…”

A three-photon absorption technique that utilizes a visible B'II(o:)-X'Z; transition followed by two-photon absorption was applied to characterize the high-lying vibrational levels of the F'O: ion-pair state of 12, which correlates with I-(IS) + I+('D) at the dissociation limit. The multiphoton spectrum was examined at high resolution using either a single tunable dye laser (3PlC), or two independently tunable pump and probe dye lasers (3P2C), operating in the bluegreen region. The one-color spectrum excited by a single laser shows transitions that have not been assigned by previous workers; these rotational lines are interpreted as being due partly to 3P1C transitions to the F'O: ion-pair state, for which molecular constants are derived to be (for

“…The ion-pair potentials were generated by interpolation from the reported RKR points. 4,21,22 In the case of =17 of the ␥1 u ͑ 3 P 2 ͒ state, 21 for which the RKR data only extend to = 11, the RKR range was extended to 2000 cm −1 with cubic interpolations in the intervals between two adjustable knot points on both branches, ensuring continuity of first and second derivatives of the potential. The aim of the simulations was prima-rily to establish R e values of the shallow-bound states, rather than modeling the precise shape of the repulsive wall of the potential or its long range behavior.…”

Structured emission in the gas phase to two weakly bound valence states that correlate with the third dissociation limit, I*(2P1/2)+I*(2P1/2), designated as (bb), from two third tier ion-pair states of I2 correlating with I-(1S0)+I+(1D2), the 1g(1D2), and F'0u+(1D2) states, has been observed for the first time. The 1u(bb) state is shown to be bound by 377+/-2 cm(-1) and molecular constants have been determined. Vibrational structure in the 0g+(bb) state could not be resolved but the spectrum is consistent with the state being bound by 435 cm(-1). The relative integrated intensities of the emissions from both ion-pair states to various valence states have also been measured, and some aspects are rationalized in terms of the electronic configurations of the upper and lower states. Bound levels of a previously uncharacterized 1g(ab) valence state have also been observed in emission from the gamma1u(3P2) ion-pair state. The lower state is shown to be bound by 270+/-2 cm(-1) and molecular constants have been determined.
