Abstract
High-order harmonic responses from three isomers: fullerene, ring, and bowl, are calculated within the modified Lewenstein model for molecular systems. Spectra for all three structures exhibit intense modulations of the harmonic spectrum along the plateau and some of them can be interpreted as a consequence of multi-center interference effects. Each structure shows characteristic modulation patterns in peak harmonic intensities, which are directly related to zeroes in the recombination matrix element as a function of the three components of momentum. Different C isomers lead to different harmonic polarizations depending on the geometric configuration of carbon atoms and molecular orientation.
