n-Butylbenzene has been pyrolysed over a range of temperatures from 300� to 900�, at 50� intervals, and the resulting tars analysed. The optimum temperatures for the formation of 15 polycyclic aromatic hydrocarbons have been determined; these range from 660� to 740�.

In an attempt to stud) the mode of formation of polycyclic aromatic hydrocarbons in cigarette tar, pyrolyses of dotriacontane (C32H66) and of stigmasterol at 700� have been undertaken. Both compounds gave complex tars containing many aromatic hydrocarbons. Mechanisms for the formation of some of these are discussed, and the relative concentrations of some of the polynuclear hydrocarbons present 1n both tars are compared with those in cigarette tar.

We show that polycyclic aromatic hydrocarbon (PAH) chromophores that are linked between two five-membered rings can access planarized structures with reduced optical gaps and redox potentials. Two aceanthrylene chromophores were connected into dimer model systems with the chromophores either projected outward (2,2’-biaceanthrylene) or inward (1,1’-biaceanthrylene) and the optical and electronic properties were compared. Only the planar 2,2’-biaceanthrylene system showed significant reductions of the optical gaps (1 eV) and redox potentials in relation to the aceanthrylene monomer.<br>
