Electron spin resonance:: A major probe for molecular conductors

For the past 30 years, research on molecular conductors led to many important discoveries and to a very large number of publications. In this review, selected results were considered to illustrate the relevance of the ESR technique in this field. Molecular conductors display a wide variety of electronic ground states including paramagnetic, ferromagnetic, antiferromagnetic, Spin-Peierls, Peierls and superconducting ground states. In all of these cases, electron spin resonance detected in these different phases, was a major probe.
