G. Theodorakopoulos et Id. Petsalakis, RYDBERG SPECTRA OF ARH - BOUND-BOUND INTERACTIONS, PREDISSOCIATION, AND RADIATIVE LIFETIMES OF THE RYDBERG STATES, The Journal of chemical physics, 101(1), 1994, pp. 194-200
Bound-bound (2) Sigma(+)-(2) Sigma(+) and (2) Sigma(+)-(2) Pi interact
ions and their effect on the rotational-vibrational levels of Rydberg
states of ArH/ArD have been investigated. Strong interactions have bee
n obtained for the B (2) Pi-C (2) Sigma(+), D (2) Sigma(+)-E (2) Pi, a
nd E (2) Pi-1 (2) Delta pairs of states in accord with recent experime
ntal analyses of Rydberg spectra of ArD. Predissociation lifetimes of
A (2) Sigma(+), C (2) Sigma(+), and D (2) Sigma(+) as well as transiti
on energies and radiative lifetimes for Rydberg states up to 4f have b
een also calculated.
