abstract = {We present an analytical method for the real-time detection
of free radicals from the photodecomposition (ultraviolet
radiation, lambda = 254 nm) of hydrogen peroxide (H2O2)
using frequency-mixing magnetic detection. We monitored the
free radicals in situ without catalysts or probe molecules.
Both water and H2O2 produced frequency-mixing signals under
UV radiation, but the water signal was much weaker. The root
mean square amplitude of the frequency-mixing signal was
found to depend on the initial H2O2 concentration.
Considering the physical properties of the reactants, the
frequency-mixing signal is attributed to the generation of
paramagnetic free radicals by the photodecomposition of
H2O2. (C) 2012 American Institute of Physics.
