We have obtained resonant 2-colour 2-photon ionization spectra of Np$_n$Ar$_m$ (Np = naphthalene). While most spectra are broad and unresolved, those of Np$_2$Ar$_m$ arouse particular attention as they appear to consist of two independent and shifted electronic spectra. We consider our experimental data in the light of proposed structures for the naphthalene dimer and offer an alternative explanation for the observed broadening of the spectrum of Np$_2$ in terms of fragmentation of higher clusters.
