✦ Synopsis

WC investrgatc the cffccts of structural disorder on the absorption line shapes of the lowest cxciton 4tatcs in molecular crystk at .xro tcmperaturc by the application of the average t-m&lx approxlmatmn to a system characterized by a gau+ am distribution of site cucikition encqgcs.

The lint shape cxhrbits asymmetric lirw broadening with the high energy portlon being close to Iorcntrran, whole the low cncrgy cdgc is sharp. The energy dcpcndcncc of the low energy tail is dcrcrmined by tlic dlmensionallty of the cxclton band structure.
