The formation of C x F 2 x +1 CH 2 C(O)OONO 2 ( x = 1,6) from the photooxidation of C x F 2 x +1 CH 2 C(O)H ( x = 1,6) in the presence of NO 2 was investigated. The infrared spectrum of C 6 F 13 CH 2 C(O)OONO 2 is reported for the fi rst time, and thermal stability for both peroxynitrates at 295 K and 9.0 mbar is informed. Kinetic parameters (activation energy and pre-exponential factor) for CF 3 CH 2 C(O)OONO 2 at 9.0 and 1000 mbar are: 108 ± 2 kJ/mol, 1.5 × 10 15 and 114 ± 2 kJ/mol, 2.4 × 10 16 , respectively. A comparison is made between fl uoro and hydrogenated peroxy acyl nitrates.
