Nuclear Magnetic Resonance of Cl35 in FeCL2
Abstract
This thesis describes an experimental study of the nuclear
magnetic resonance spectrum of Cl35 in a single crystal
of FeC12. This crystal has an essentially cubic close-packed
structure with trigonal distortion and an axially symmetric
electric field gradient. The field gradient direction is
perpendicular to the layers of Cl atoms which sandwich the
layers of Fe atoms. The C135 nucleus, with spin 3/2, has an
electric quadrupole moment which interacts with the electric
field gradient to cause large splittings of the pure Zeeman
levels. There is also a presumably small isotropic and anisotropic
paramagnetic shift.
