Using QLCR to Study Stopping Sites in Molecular Solids

Muon nuclear quadrupolar level crossing resonance is not a well-known technique, however it is extremely powerful. There is a large interest in probing the muon stopping site and the behaviour of molecular solids where the elusive diamagnetic muonium fraction is present. For this to work you require a nuclei where I>1, and then the resonance field relates to the electric field gradient across the nuclei. QLCR has been performed on nitrogen and this has been successful, we seek to expend this to molecular solids where there are CN groups present, which are isoelectronic to nitrogen. This will present us with a way to not only probe the muon stopping sites and relate this to physical properties.
