Procédé pour spectroscopie RMN d'échantillons solides
A method for performing magnetic resonance spectroscopy on solid sample containing nuclei of interest with spin quantum number I, comprising: subjecting the sample to a static magnetic field, spinning the sample at the magic angle and broad-band excitation of transverse magnetization of the nuclei of interest, is characterized in that broad-band excitation is carried out by applying a first train of rotor-synchronized rf-pulses with a carrier frequency to the nuclei of interest with a pulse duration 0.1 µs < t p < 2 µs, the first train of rf-pulses comprising k·n pulses extending over k rotor periods t rot with n pulses per rotor period t rot, where n is an integer n > 1. With the inventive method uniform excitation of a great number of spinning sidebands or families of sidebands that arise from large first-order quadrupole or hyperfine interactions is enabled and signal intensity can be improved.
