Interaction between chiral molecules and solvents: The importance of an interface

The recently introduced hypothesis of chiral interaction is shown here to require an additional constraint of an interface between two media in the close vicinity of the chiral molecule or element. As a result only the induced intramolecular current can exist under this constraint whereas the induced mechanical rotation is ruled out. The energy associated with this current is estimated to be of the order of (10⁻⁵–10⁻⁴)kT. Possible thermodynamical consequences of the chiral interaction for small systems are discussed.
