Abstract

Abstract Pulse radiolysis was used to study the kinetics of the reactions of CH 3 C (O) CH 2 O 2 radicals with NO and NO 2 at 295 K. By monitoring the rate of formation and decay of NO 2 using its absorption at 400 and 450 nm the rate constants k (CH 3 C (O) CH 2 O 2+ NO)=(8±2)× 10− 12 and k (CH 3 C (O) CH 2 O 2+ NO 2)=(6.4±0.6)× 10− 12 cm 3 molecule− 1 s− 1 were determined. Long path length Fourier transform infrared spectrometers were ...
