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 (19)^F sites at room temperature and at 77 K. The distinct frequency shifts of the two lines appear to arise from 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.
