Zusammenfassung, Abstract
The transition probabilities, the dissociation widths, and the associated Fano parameters for rovibronic lines with J′′=0,...,3 of the absorption bands of the B′′B1Σ+u state out of the X1Σ+g v′′=0 ground state were measured over the complete vibrational progression, showing clearly that only the inner-well state with B′′ 4pσ character can absorb vuv light and predissociate efficiently. The absolute values of these transition probablities, predissociation widths, and Fano parameters were found to agree well with ab initio calculations if one takes into account that the calculations neglect nonadiabatic couplings.
