Abstract

We have studied the dynamics of paramagnetic CuF2 · 2H2 O using a wide range of 1H and 19F NMR frequencies at room temperature. The temperature dependence of the spin-lattice relaxation was measured as well. Being a system of dense paramagnetic Cu++ ions, CuF2-2H20 shows some features that can be expected from dilute paramagnetic systems, as well as some results that drastically deviate from the dilute paramagnetic approximations. Besides, ∗H and 19F nuclei exhibit distinct external magnetic field dependences of the linewidth and the spin-lattice relaxation.
