We also study advanced or complex materials
such as intrazeolite systems, atomic-sized semiconductors, and pharmaceutical
compounds, in collaboration with a number of other research groups who
speciallize in the synthesis of these materials. Such materials are challenging
to study because of their complex and heterogeneous nature, and their
spectra often consist of overlapping or broadened lines. This problem
may be circumvented by spreading the spectra into more than one dimension,
thereby increasing the resolution dramatically. In this way, solid-state
NMR methods can probe the structure of an enormous variety of compounds
and advanced materials and interrogate their dynamics in a broad range
of time scales. Similar methods are used to gain information on the complex
behavior of pharmaceutical compounds that are formulated in a variety
of structures ranging from amorphous to polymorphic. Magnetic resonance
methods are ideal to study the structural and dynamical behavior of such
materials in order to characterize their viability as potential candidates
for further development.
