Changes in absorbance at 100 K occurring upon irradiation of 35 mg ml-1 HEWL solutions in cryobuffer, with (c and d) and without (a and b) 0.5 M lithium nitrate. (a and c) Absorption spectra at a dose of 0 MGy (blue) and 0.078 MGy (purple). (b and d) Changes in normalized absorbance with time at certain wavelengths of interest. A 1 s X-ray exposure gave an absorbed dose of 0.02 MGy.  [article HTML]
