HYPERFINE STRUCTURE IN THE B3Π+Ou STATE OF I2 CLOSE TO THE DISSOCIATION LIMIT
Résumé
The excitation spectrum of a supersonic beam of I2 is explored at ∼ 1 MHz resolution for vibrational levels (υ′−75−81) close to the dissociation limit of the B3Π+Ou state (499.5-500.0 nm). The hyperfine structure is analysed and shows the expected theoretical trend. The analysis of perturbed lines is now in progress in order to localise the potential curves of these previously unobserved perturbing states sharing the same dissociation limit as B3Π+Ou.
