Abstract 15N solid state NMR without enrichment is rarely used because of the low sensitivity and low natural abundance of this nucleus. As demonstrated on different nitrogen-containing polysilanes and polysilazanes, it can be shown that with the CP/MAS technique spectra can be obtained in good quality and within acceptable measuring time. Three main different nitrogen sites – NSi3, NSi2H and NSiH2– can be observed as well as changes in the intensities of these sites with reaction and tempering conditions. Thus the spectra give valuable additional information for a better understanding of the structures and their changes within the investigated systems.
