摘要: We have observed the ΔMs = 2 spectra due to radical pairs in a number of typical polymers irradiated at 77°K. The formation is not particular phenomenon some crystalline solids. crystallinity does affect an apreciable amount. buildup curve suggests that pairwise trapping occasional overlapping spurs and there intrinsic value formation. hyperfine separation polyethylene polypropylene values which are half those isolated radicals. This means paired radicals probably two alkyl trapped pair. urea addition compounds did give any signal spectra.
