Cyclic PON, a first 16‐electron triatomic ring consisting of two first‐row elements, has been generated through 193 nm laser photolysis of OPN in cryogenic matrices. When the photolysis (365 nm) was performed in the presence of CO, OPN combines CO and furnishes an exotic acyclic molecule OPNCO. Upon the 193 nm laser irradiation, OPNCO dissociates mainly to OPN and CO with traces of PN and CO2. The identification of cyclic PON and OPNCO with IR spectroscopy is supported by 15N‐labeling experiments and quantum chemical calculations.
