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
Using a self-consistent NMR method, it is now possible to determine both the deuterium quadrupole coupling constant as well as the rotational dynamic isotope effect in liquids. We successfully tested the method on benzene for temperatures between 280 K and 293 K. The average value of 185(3) kHz for
