The spectral signatures of Frenkel polarons in H- and J-aggregates.
TL;DR: This Account shows that the aggregation-induced deviations from the Poissonian distribution of vibronic peak intensities take on two extremes identified with ideal H- and J-aggregates, and reveals several more distinguishing traits between the two aggregate types.

Studies of polaron motion: Part I. The molecular-crystal model
TL;DR: In this paper, a model for polaron motion is described, in simplified form, incorporating the principal physical features of the problem, and the conditions under which the size of the polaron becomes comparable to a lattice spacing (small) are discussed.
