— Tests for the possible catalytic role of fluorescers in the chemiluminescent decomposition of dioxetanes are discussed and applied to the case of tetramethoxydioxetane. This dioxetane, which can undergo direct thermal decomposition yielding excited methyl carbonate with subsequent excitation of fluorescers (for example 9, 10‐dibromoanthracene. DBA), is shown to be sensitive also to catalysis by fluorescers such as rubrene. 9, 10‐diphenyl‐anthracene (DPA) and 9, IOdicyanoanthracene (DCNA). The possibility of a charge‐transfer mechanism of chemiluminescent catalysis is suggested.
