Critical dynamics of conformational exchange in a near-critical solvent: A statistical-mechanical three-mode theory.

We develop a three-mode statistical-mechanical theory for a two-conformer solute in a near-critical solvent. A compressible lattice model with vacancies yields the Gaussian free-energy functional for a critical conserved density, an orthogonal noncritical conserved mode, and the local conformer fraction. Their coupling...
