Preferred Label : interfacial layer;
IUPAC definition : The inhomogeneous space region intermediate between two bulk phases in contact, and
where properties are significantly different from, but related to, the properties
of the bulk phases. Examples of such properties are: compositions, molecular density,
orientation or conformation, charge density, pressure tensor, electron density, etc.
The interfacial properties vary in the direction normal to the surface. Complex profiles
of interfacial properties occur in the case of multicomponent systems with coexisting
bulk phases where attractive/repulsive molecular interactions involve adsorption or
depletion of one or several components. This interfacial region may also be regarded
as a distinct, though not autonomous, phase and be called the interphase.;
