Default How to obtain a good COSY spectrum of a paramagnetic compound
How to set up the experiment in order to obtain a good COSY spectrum of compound that containing Cu(II), which should hyperfine shift from 150ppm to -50 ppm?

I have tried to do it by just changing the spectrum width of both dimension, with an hour of acquistion time, but no cross peak can be observed between any signal.
