(A) Model g_c(r)’s describing gas and cluster forms of NALA correlations in solution. The gas phase g_c(r) corresponds to a Lennard-Jones interaction between solute molecules represented as spheres of σ = 5.0 Å with ɛ = 1.6 kcal/mol. The cluster g_c(r) is the same as the gas phase except for a second peak position at 2σ. (B) A comparison of the excess experimental signal with the simulated solute–solute scattering derived from the various models of g_c(r) shown in A. The comparison emphasizes that the gas and cluster forms of g_c(r) are probably not viable representations of the solute–solute correlations.
