Spectral assignment: To evaluate the possible role of dibenzorubicene in interstellar phenomena, the laboratory absorption (IR to VUV) and emission (vis) spectra of this PAH were measured under different conditions. UV/vis absorption spectroscopy has been carried out at cryogenic temperatures in Ar and Ne matrices (see picture). All spectra were analyzed with support of theoretical results obtained with semiempirical, ab initio, DFT, and TDDFT methods.
