Fig. 1. Evaluation of the measured transition enthalpy ΔHu by eqn (8). (a) ΔHu as the function of salt concentration cs. The marks show the experimental data for the unfolding of ribonuclease in presence of the salts indicated in the graph. These data have been taken from Table 1 of Francisco et al.18 (b) ΔHu as the function of ΔTm = Tm − T0m. The solid lines indicate the fit of eqn (8) whereas the green dashed line indicates the transition enthalpy calculated by eqn (8) with the average value Δcp,0 ≅ 4.6 kJ (K−1 mol−1) and dΔcp/dcs = 0. See text for further explanation.
