Predissociation by internal rotation

Predissociation By Internal Rotation Vibrational Predissociation With Av=0... 

Results and Predictions. Detailed close coupling calculations for "real" Av<0 vibrational predissociation of weak-coupling systems such as the hydrogen-inert gas complexes are more difficult and computationally more expensive than those for predissociation by internal rotation. The computational expense arises simply from the very large increase in the nvmber of channels which must be included in order to obtain converged results. The difficulty, on the other hand, arises from the fact that these resonances have very small widths, usually 10 cm , %jhich makes them very difficult to find. 

Calculations analogous to those of Table V have not yet been reported for complexes of hydrogen with other inert gases. However, our experience with the case of predissociation by internal rotation and our understanding of the potential energy surfaces involved should allow us to make reliable predictions reqarding the trend from one system to the next.
