Abstract: The enhanced 51V NMR in Al 2O 3 and [C(NH 2) 3]Al(SO 4) 2· 6 H 2O have been studied. Both systems are Van Vleck paramagnets. Analysis of enhanced 51V NMR and V 3 + ESR data allowed us to estimate vanadium nuclear quadrupole frequencies and hyperfine interaction constant B for 51V 3 + ions in corundum for the first time.
