(A) Experimental spectra at 77 K of phosphorus-centered radicals in Kr-86 ion beam irradiated (at 77 K), hydrated DNA. The dashed line is the sum of the simulated spectra in B and C. (B) Simulated spectrum (for parameters see text) of the main phosphorous-centered radical, ROPO2•−. (C) Simulated spectrum of unknown phosphorous-centered radical (Px).
