title: Isotopomer encapsulation in a cylindrical molecular capsule: a probe for understanding noncovalent isotope effects on a molecular level.
abstract: Isotope effects for the encapsulation of deuterated versus nondeuterated guests are determined. This system involves the use of social isomers, and the origin of the isotope effect is localized to methyl groups interacting with aromatic rings.
