Fig. 2 Comparison of the normalized differential distributions of sedimentation coefficients, c N(s), of γ-CD in H2O (1), DMF (2), and DMSO (3), as obtained with the Sedfit program. For clearness each distribution is normalized on the maximal value of c max(s) such as c N(s) ≡ c(s)/c max(s) to eliminate the influence of different increments of refractive indexes
