The microscopic magnetic properties of the paramagnetic state in the triangularHeisenberg antiferromagnet VX. (X=C], Br and I) have been investigated byusing the NMR technique. From the "V shift vs the magnetic susceptibilityplot the hyperfine coupling constant due to the d-spin core polarization effect isdetermined to be -95i2, -79-3-2 and -69#2 k0e/un for VCI2, VBrz and V12,respectively. Also it has been revealed that the high temperature value of the "Vnuclear spin-lattice relaxation rate is explained from the Guassian model for theauto-correlation function of the spin fluctuations.
