The nitrogen vacancy (NV) centre in diamond offers the intriguing opportunity to provide an atomic sized sensor with very high sensitivity. Recently it has been shown that it is even possible to sense the magnetic field of a single spin at ambient conditions. We aim to extend previous measurements to high magnetic fields, where the NV’s sensitivity may enable detection of chemical shifts at a single molecule level. Since the chemical shift depends on the external magnetic field we conceptualize a cooperated setup consisting of a confocal microscope and a superconducting magnet operating at several Tesla. This also includes the designing of structures to control the position of the target molecules as well as microwave resonators to coherently control the spin NV system at high magnetic fields.
