Abstract
The experimental observation of spin waves by NMR spectroscopy is repo rted for a linear chain consisting of five scalar coupled C-13 spins o f lysine. Selective excitation of a first spin and evolution under an effective planar zero-quantum Hamiltonian with terms 2 pi J(i,i+1)(Iix Ii+1,x+IiyIi+1,y) leads to the propagation of a damped spin-wave packe t bouncing back and forth at the chain ends. The effective planar Hami ltonian is generated by the application of a multiple pulse sequence.
