The technique of nuclear magnetic pulsed double resonance in the rotating frame has been used to determine the quadrupole interactions of 14N in a single crystal of glycine nt 140Β°C. The 1% quldrupole coupling constant is found to be very small e%Q/fz = ;-%5kHz. whereas the ssymmetry paczmeter is re

β¦ Synopsis
Using doubIe nuclear resonance techniques (DRLC) the quadrupole resonances spectrum of 14N is obtained in both protonated and deuterated glycine crystallized in each of three crystalline forms. In the deuterated samples the quadrupole resonance spectrum is obtained for each of the three amino deuterons again in each of the three crystalline forms. It is suggested that this system is ideal for a comparison between theoretical calculation and experiment measurement of molecular electric fIeId gradients.
