Luminescence of ion-pair states of halogens in liquid perfluorocarbons.
The I(2)(D'-A') luminescence in liquid C(7)F(16), C(8)F(18), C(9)F(20), and C(12)F(26) has been observed following irradiation with visible (within the I(2) X → B band region) and UV (λ < 300 nm) lasers. The band is shifted by ~2000 cm(-1) to the red relative to the gas phase and is significantly broader (fwhm ≈ 3000 cm(-1) vs 500 cm(-1) in the gas phase). Two-color excitation of other halogens...
متن کاملNonadiabatic Electronic Interactions In The Ion-Pair States Of NelCl
Nonadiabatic interactions in the NeICI van der Waals complex have been explored in the lowest energy triad ofICI ion-pair states (~39 000 cm-I). Dispersed fluorescence measurements reveal emission characteristic of multiple ion-pair electronic states, with the relative contributions from the E(0 +), P(1), and D I (2) states changing with the initial ICI vibrational excitation (VICI)' Emission d...
متن کاملO , Ion - Pair States , and Oxygen Atom Recombination
Collisions of oxygen or nitrogen molecules with laser-excitated high vibrational levels of O ) produce a longer lived excited state, whose resonant multiphoton ionization (REMPI) spectrum cannot be assigned to any known singlet or triplet system [1]. We attribute the lower state of this new transition to the predicted [2,3] but previously unobserved valence state of O . The regular sequence of ...
متن کاملRole of ion-pair states in the predissociation dynamics of Rydberg states of molecular iodine.
Using femtosecond pump-probe ion imaging spectroscopy, we establish the key role of I(+) + I(-) ion-pair (IP) states in the predissociation dynamics of molecular iodine I2 excited to Rydberg states. Two-photon excitation of Rydberg states lying above the lowest IP state dissociation threshold (1st tier) is found to be followed by direct parallel transitions into IP states of the 1st tier asympt...
