✦ Synopsis

By using spool configurations of a sample containing aluminum foil, in which the axis of the spool is collinear with the RF coil axis, one can obtain high-quality 13 C NMR spectra of static samples of organic material attached to the aluminum Ž foil. By combining such a spool configuration or, alternatively, analogous samples containing equivalent amounts of fine . Ž . aluminum powder with the magic-angle hopping MAH technique, one can achieve a high degree of isotropic averaging of the 13 C spectrum. This opens to NMR techniques the study of a variety of samples containing macroscopic pieces of metal foils, e.g., thin films deposited on metal foils and electrochemical systems with species adsorbed on metal-foil electrodes.
