摘要：

Natural abundance **1**5N NMR of solids has been demonstrated as a useful characterization tool for polyamides. In addition to copolymer composition differences, glassy amorphous conformations and crystal forms can be examined in the solid phase which are not observed in solution. **1**5N CP-MAS NMR provides a new method for determining the crystal structures of nylon-6 samples. The greater sensitivity of nitrogen to its environment in solid-state NMR compared to carbon opens up a broad area for study of crystalline polyamides.
