The dissociation of nitrogen in a 2.45 GHz microwave plasma has been significantly enhanced by the application of a magnetic field perpendicular to the oscillating electric field. The degree of dissociation measured in the emergent beam was found to be strongly dependent on the magnetic field strength, nitrogen pressure and microwave power. These results have been interpreted in terms of microwave absorption resonances. Dissociation fractions up to 0.67 have been measured.
