PULSE SEQUENCING WITH HYPERPOLARISABLE NUCLEI

摘要

There is described a method of selective observation of non-hydrogenative para- hydrogen induced polarisation (NH-PHIP) as enhanced magnetic resonance signals which comprises separating the thermal and longitudinal spin order states. There is also described a template comprising [Ir(COD)(NHC)(Py)]+, and analogues thereof, for use in a PHIP magnetic resonance technique and a method for its preparation.
