• The kinetics of the addition reaction of O2 to the tert‐butyl radical has been investigated at 1.5 bar as a function of temperature (241–462 K) using the muon spin relaxation technique in longitudinal magnetic fields. The data are represented by kch = 43+88‐26 X 10−10T−0.96±0.21 cm3 molecules−1 s−1, or alternatively by an Arrhenius activation energy of −2.4(0.7) kJ mol−1 and an apparent frequency factor of 68(19)x10−13 cm3 molecules−1 s−1. The results of these temperature‐dependent measurements agree well with an experimental literature value at room temperature, but disagree with a more recent estimate by a factor of six.
