Abstract

In this paper we propose a novel approach for the deconvolution of the complex spectral structure of the S0→,S1 electronic spectra of aromatic molecule-rare-gas heteroclusters, which rests on the experimental observation of isomer-specific radiative lifetimes of structural isomers at a fixed composition. The spectra and the pure radiative lifetimes, τr, of 9, 10-dichloroanthracene·Krn (n = 1-5) heteroclusters were measured by resonant two-photon two-color ionization. Different τr values for distinct spectral features of n = 3-5 heteroclusters with a fixed n allow for the distinction between structural isomers. The confrontation between experiment and a molecular theory of τr provides an unambiguous identification of the structural isomers of heteroclusters.
