The photolysis and pyrolysis of the title compound leads to, among other products, cyclobutane ring systems with crossed or parallel bonds; photolysis affords also such systems transfused to a cyclopentanone. Isogermacrone is found to be present in small amounts in the essential oil of Geranium macrorrhizum L.
