Studies of Solutes with Internal Rotors,nique have been extensively discussed (1). We review briefly the difficulties: the spectral complexity limiting the analyzable spin systems, the solute-solvent interactions and the difficult rationalization of the data in terms of separate structural and orientational parameters.

Molecular Structure from Dipolar Coupling, is based on the last term of the following effective Hamiltonian: . where . is the well known indirect coupling constant and . is the sum of the pseudo dipolar coupling, ., and the dipolar or direct coupling D.. The dipolar coupling is defined as

On the Orientation of Small Molecules in Anisotropic Solvents,sy to account for the effects of internal motion completely satisfactorily. For solutes with large-amplitude intramolecular motions the problem of how to treat their average orientation has given rise to some controversy. A first attempt to phrase the problem in terms of a kinetic approach in which

Multiple Quantum NMR in Liquid Crystalline Phases,issolved in mesogenic solvents, magnetic interactions are functions of geometric factors and order parameters. The geometric factors relate elements of a magnetic interaction tensor in some principal axis system (pas) to a molecule-fixed frame, and so provide information on molecular structure, whil
