The Nonresonant DST Equation as a Model for McClare’s Excimer

In the contribution by Knox et al. to these proceedings, it was emphasized that the mechanism for injecting energy into—and extracting it from—the alpha helix region has not yet been adequately considered. They suggest that this question deserves as much theoretical effort as the problem of calculating soliton lifetime. A similar concern was noted by the present author several years ago [1]. Introducing an arbitrary perturbation of the sound system in Davydov’s equations, it was shown that only the (kinetic) energy of motion would be converted to mechanical energy, not the rest energy. Other mechanisms, it was concluded, must be supposed to make use of the main portion of soliton energy. The aim here is to consider one such mechanism: McClare’s “excimer” [2].
