Large polycyclic aromatic hydrocarbons (PAH's) have recently been suggested to be abundant in the interstellar medium surrounding carbon rich stars.To aid in the identification of the species responsible for the astronomical UV and IR data, a new synthesis is reported for hexa-peri-benzocoronene and its dimethyl derivative.The UV, fluorescence, phosphorescence, photoelectron and IR spectra of this extremely stable hydrocarbon are presented and compared with the available astronomical spectra.Experiments useful to check the PAH hypothesis are suggested.
