摘要: Abstract Porous silicon has been characterized by 29Si nuclear magnetic resonance spectroscopy under conditions of static samples, magic angle spinning, decoupling and cross polarization. In a free induction decay experiment, two resonances at −80 −111 ppm were obtained. Cross polarization resulted in single −97 ppm. Magic spinning slightly reduce the linewidth polarized signal. The minor narrowing effect relaxation behavior laboratory rotating frame indicate homogeneous contribution to linewidth. data suggest that observed arises from SiH or SiH2 structural elements.
