The traditional method of analyzing solution structuring properties of
solutes using atom-atom radial distribution functions (rdfs) can give
rise to misleading interpretations when the volume occupied by the so
lute is ignored. It is shown by using the examples of O(4) in alpha- a
nd beta-D-allose that a more reliable interpretation of rdfs can be ob
tained by normalising the rdf using the available volume, rather than
the traditional volume of a spherical shell. (C) 1998 John Wiley & Son
