We have studied the paramagnetic CuF2 using the techniques of pulsed nuclear magnetic resonance (NMR). The powder sample revealed two well-separated lines from the distinct 19F sites at room temperature. One of the lines showed little frequency shift. However, the other showed a large frequency shift, suggesting electron transfers. Furthermore, the two sites have very short spin-lattice relaxation times (T1). The frequency-shifted site has the shorter T1 than the unshifted one, reflecting the difference of the electron environments of the two sites.
