Clathrate-like structure of water around some nonelectrolytes in dilute solution as revealed by computer simulation and X-ray diffraction studies

An X-ray diffraction measurement has been carried out for a 3.9 mol% aqueous solution of TBA (tertiary butylalcohol) with an energy-dispersive diffractometer. Constant temperature molecular dynamics calculation has also been made for an aqueous solution model simulating the above-mentioned mixture. Both results suggest the formation of a fairly stable clathrate-like structure of water around TBA molecules.
