Static properties of Cu2+(3d9; S=1/2) spins in a new class of quantum spin system, a twisted Heisenberg triangular spin tube, [(CuCl2tachH)3Cl]Cl2, have been investigated by using nuclear magnetic resonance (NMR) in a temperature region of T=0.05-300 K. An observation of magnetic broadenings of 1H-NMR spectrum at low temperatures directly revealed a gapless ground state of the system.
