A coil system is disclosed which is particularly suitable for volume-selective MR spectroscopy. In addition to the coil for generating the RF pulses and for receiving the MR spin resonance signals, the coil system comprises a correction coil which receives a direct current so that this coil generates an inhomogeneous field which compensates for inhomogeneities of the steady magnetic field in the selected volume. As a result, the magnetic field in this zone becomes homogeneous to such an extent that spectroscopic examinations can also be performed in zones in which the magnetic susceptibility varies strongly in space.
