Densities, rho, and viscosities, eta for glycine, L-alanine, L-valine and L-phenyalanine in 0.01 mol . kg (1) aqueous solutions of hydroxypropyl-beta-cyclodextrin have been measured at T = (293.15, 298.15, 303.15 and 308.15) K. From these experimental results, the apparent molar volume, V-phi, limiting apparent molar volume, V-phi(0) and the slope, S-V, transfer volume, Delta V-phi(0), limiting apparent molar expansibility, phi(0)(E), hydration number, n(H), Falkenhagen coefficient, A, and Jones-Dole coefficient, B, were calculated. The results are interpreted in terms of (solute + solvent) and (solute + solute) interactions in these systems. The trends in transfer volume Delta V-phi(0) have been interpreted in terms of (solute + solvent) interactions based on a co-sphere overlap model and (host + guest) interactions.
