✦ Synopsis

A semiclassical analysis of quantum-mechanical resonance lifetimes provides a framework for describing unimolecular dissociation rates near or below the adiabatic thresholds associated with saddles on potential energy surfaces. A formula which can be used when only one channel is effectively open is derived. The behaviour of resonances supported by two interacting states is briefly studied as a function of the coupling strength.

The development of commercial biosensors based on surface plasmon resonance has made possible careful characterization of biomolecular interactions. Here, a set of destabilized human carbonic anhydrase II (HCA II) mutants was investigated with respect to their interaction kinetics with two different
