Predissociation linewidths in the spectrum of gallium nitride

Predissociation of the rotationless vibrational states supported in the potentials of the 3Π(II) and 3Π(III) electronic states of gallium nitride is investigated. The linewidths for predissociation caused by spin-orbit interactions of arbitrarily chosen strength between the 3Π(II) state and the 5Σ−(I) state, between the 3Π(III) state and the 5Σ−(I) state and between the 3Π(II) state and the 5Π(I) state are calculated by the semiclassical method to provide data for the purpose of determining the interaction strengths by comparison of the calculated linewidths with experimentally measured values.
