A theory for the quantitative interpretation of nuclear Overhauser effects (NOE) in multispin systems is presented and applications to the determination of molecular configurations in solution are discussed. The NOE between several of the protons of 2', 3'-isopropylidene-3, 5'-cycloguanosinehave been measured and are interpreted to illustrate the use of the theory to measure relative interproton distances. The computed distances were within 5-10% of the distances measured on molecular models constructed using bond lengths and angles known by X-ray diffraction for a similar compound, 3, 5'-cycloadenosine iodide. The experimental and theoretical problems of using the NOE for conformation studies of molecules in solution are discussed.
