Abstract
The emission spectra of highly excited one-dimensional Frenkel exciton s are obtained from the correlation functions of a quantum spin chain. The system-size dependence of the emission intensity reflects critica l exponents of the spin system that also characterize statistical prop erties of Frenkel excitons intermediate between bosons and fermions. E xact expressions for these spectra show blue shifts of emission peaks and fine structure due to finite-size effects.
