CF 3 OC(O)OO radicals are generated by low‐pressure flash thermolysis of CF 3 OC(O)OOOC(O)OCF 3 highly diluted in inert gases and followed by subsequent isolation in an inert‐gas matrix at low temperatures. The by‐products CO 2 , COF 2 , CF 3 O, and CF 3 OO are detected. The new peroxy radical is characterized by IR and UV spectroscopy and by its UV photolytic decay which leads to the formation of CF 3 OO and CO 2 . According to DFT calculations the existence of three stable rotamers is predicted and two of them are found experimentally.
