Two Dimensional Hyperfine Sublevel Correlation (HYSCORE) Spectroscopy: Powder Features for S=1/2,I=1

摘要

The lineshapes of two-dimensional magnetic resonance spectra of disordered or partially-ordered solids are dominated by ridges of singularities in the frequency plane. The positions of these ridges are described by a branch of mathematics known as catastrophe theory concerning the mapping of one 2-D surface onto another.
