H2 ion in a strong magnetic field: Lowest gerade and ungerade electronic states
In framework of variational method with a single trial function an accurate study of the lowest gerade 1g and ungerade 1u electronic states of the molecular ion H 2 in a magnetic field ranging 0− 4.414× 10 13 G for an arbitrary orientation angle of the molecular axis 0 ≤ θ ≤ 90 is performed. Oneparametric gauge dependence in the Hamiltonian is introduced then variationally optimized. A well pro...
متن کاملDouble-well states of ungerade symmetry in H2: first observation and comparison with Ab initio calculations.
The observation of a new class of long-lived outer well states of ungerade symmetry (B"B1Sigma+u) in molecular hydrogen, lying above the ionization threshold, is reported. Rovibrational levels within a potential extended over internuclear separations of R = 7-25 a.u. are experimentally investigated in a triple resonance scheme. Good agreement ( <0.5 cm(-1)) with updated ab initio calculations i...
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...
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 کاملLuminescence 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...
