Measurements on single crystals of lower symmetry doped with NpO or PuOl" " should remove this uncertainty but no such experiment has been performed so far. However, the distinction between configurations (a) and (b) has been possible in an electron paramagnetic resonance study at 20 K on a single uniaxial crystal of RbU02(N03)3 doped with plutonyl ions. This study conclusively showed that the ground state is H4 with gy = 5.4 and g = 0 28).

Electron paramagnetic resonance studies have shown that the biacetyl ketyl radical (3) and the radical derived from dioxane are formed when biacetyl is irradiated in dioxane solution.51 Nonphotochemically generated radicals derived from dioxane and cyclohexane add to biacetyl to yield acylated product.56 If cleavage were occurring in addition to or instead of hydrogen abstraction, one would expect to find at least moderate yields of acylated products in all solvents instead of just those which produce the least stable solvent radical.

AgSiS can be prepared by reaction of silver atoms with molecular SiS. Studies of AgSiS in both hydrocarbon matrices (electron paramagnetic resonance study)125 and solid argon126 demand a triangular structure with a Ag—S bond (similar to the structure of AgSiO cf Section V.B). 

Electron Paramagnetic Resonance studies Analysis by electron paramagnetic resonance spectrometry (EPR) showed the electrophoresis fraction to contain stable free radicals. A strong EPR signal was obtained at the g factor value of 2.0035-0.0003. The involvement of free radicals in the Maillard reaction has previously been reported (16). Recently also Lessig and Baltes (17) reported the content of extremely stable free radicals in melanoids obtained from the reaction between glucose and 4-chloroaniline.
