	abstract = {Photolysis of 9,10-dihydro-9,10[1{\textquoteright},2{\textquoteright}]benzenoanthracene-1{\textquoteright},4{\textquoteright}-quinone C20H12O2, in oxygenated acetone gives the novel photoproduct 9,10-dihydro-9,10-ethanoanthracen-11-one-12-spiro-2{\textquoteright}-cyclopent-4{\textquoteright}-ene-1{\textquoteright} ,3{\textquoteright}-dione, C20H12O3. The reactant quinone molecule has ideal mm symmetry and lies on a crystallographic mirror plane in Pnma; the photoproduct molecule has ideal m symmetry, which is not utilized in packing in Pna2(1). This product is formed only in the presence of oxygen and a mechanism for its formation is proposed. Unreactivity in attempted solid-state photolysis can be rationalized in terms of crystal packing.},
