Abstract
Cold neutron inelastic scattering experiments have been performed on dilute aqueous solutions of (CD

)

COH and of solutions of (CH

COH in D

O at 21 °C. From the broadening of the quasi-elastic peak and independently determined self-diffusion coefficients (
D
), diffusive lifetimes (
c
) of H
2
O molecules have been calculated as functions of solute concentration. The product
Dc
is insensitive to concentration, giving a mean diffusion step length of 0.14 nm. The inelastic portion of the spectrum, reflecting lattice-like hydrogen bonding modes indicates that the solute enhances the water ‘structure’ but that such structure bears no resemblance to ice.
