    • Note that in all of the fractionated bright states which have been studied in this paper, two nearly perfect interference effects have been observed. In each fractionation pattern, the bright state appears to be perturbed by only one state, despite being strongly coupled to two Darling-Dennison perturbers. In addition, one of the two (prediagonalized) Darling-Dennison perturbers is itself strongly perturbed via a 3,245 resonance, while the other is almost entirely unaffected. These two interference effects are, of course, intimately related, since each can be described by the simple 4-level model. The key conceptual element of this model is the prediagonalization of the two Darling-Dennison perturbers, which are coupled by vibrational l-resonance. Thus, the double interference effect may suggest that a "dressed basis set," in which the vibrational l-resonance is prediagonalized and "absorbed" into the basis set, may be more appropriate for describing the dynamics in these polyads, and perhaps others. [Such an approach has recently been explored by Kellman and co-workers (M. E. Kellman, private communication).]
