摘要：

Proton NMR experiment has been performed in CuCl2(gamma-picoline)(2) up to 9 T for the study of S = 1/2 quantum spin-gap in the one-dimensional antiferromagnet (1-D AF) with bond alternation. It is shown that the proton NMR spectrum as well as the proton spin-lattice relaxation is characterized by the singlet-ground-state. Furthermore, NMR results suggest the existence of the paramagnetic spin around the end of the finite chain.
