The title molecule, C20H15NOS, adopts an (ES,ZO) conformation, similar to that of other monothioimides, with an intramolecular O
C(S) contact of 2.821 (5) Å; a photochemical cleavage reaction probably proceeds via intramolecular nucleophilic attack of oxygen on the C=S double bond in the presence of solvolytic agents.
