A Method of Measuring Antioxidant Capacity
In a previous experiment (RB910492) we have made preliminary measurements of the rates of addition of muonium to vitamins C and E, as suggested by the ISIS panel. These rates... -
Kinetics of Hydrogen Abstraction by Mu Reactivity with Propane studied by RF ...
Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit... -
Kinetics of Muoniated Radicals Studied With Radio Frequency Muon Spin Resonance
Radio-frequency muon spin resonance is a powerful technique for studying free radicals and their reaction kinetics, but it has not yet been used to study complex reactions in... -

Many room temperature ionic liquids (salts with melting points near room temperature that hereafter will be referred to as ionic liquids) are ¿green solvents¿ for chemical... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
Artificial [FeFe]-Hydrogenases and Muon Spectroscopy
Preliminary measurements of [FeFe]-hydrogenase model complexes were made in a previous experiment using EMU (RB 1010177). The results were interpreted in combination with DFT... -
Dynamics of Perfluoroalkanes and Polytetrafluoroethylene
In this experiment we will use the F-mu+-F state as a window into the dynamics of perfluoroalkanes and polytetrafluoroethylene (PTFE) at the molecular level. We will investigate... -
Repolarization of Radicals in Liquids
The recovery of the muon polarization in a longitudinal magnetic field has been used to obtain the muon hfcs of organic radicals. In pure benzene there is a single step in the... -
