Fig. 4. NIR MCD studies of ΔHis4. The 5 K, 7 T NIR MCD spectra of ΔHis4/Ca(ii)/Fe(ii) in (A) glycerol and (B) sucrose glasses. Saturation magnetization data (dots) and best fit (lines) for ΔHis4/Ca(ii)/Fe(ii) in glycerol collected at (C) 8905 cm–1, (D) 7810 cm–1 and (E) 5880 cm–1. The low-energy tail transitions were not included in the fits as only part of the transition was observable.
