Mass Spectrometry Facility The University of
Notre Dame Mass Spectrometry (MS) Facility
provides instrumentation and expertise for the
analyses of both small and large molecules. In
early 2009, an expanded and upgraded facility
will relocate to newly renovated space in the
Department of Chemistry Biochemistry. The MS
Facility gladly welcomes samples from outside
Notre Dame. For more information, please visit

Center for Nuclear Magnetic Resonance The Center
for Nuclear Magnetic Resonance Spectroscopy (NMR)
at the University of Notre Dame supports new and
ongoing research in chemistry, chemical
engineering, biochemistry, molecular biology and
related fields. Our instrumentation enables us to
perform state-of-the-art multinuclear,
multidimensional high resolution NMR experiments
at various field strengths and temperatures to
determine the molecular structures and dynamics
of a wide range of compounds. X-Ray Diffraction
Facility The X-Ray Diffraction Facility at the
University of Notre Dame (X-Ray) provides for
X-Ray structural studies of small (ca. 2kDa)
molecules. X-Ray has the capability to examine a
wide range of molecules from light atom
biologically relevant to metal-complexed
compounds which can be readily analyzed using
non-destructive techniques.

nitrosyl (NO) in heme (iron-porphyrin)
mimics - NO identified in a number of
biological signaling/control mechanisms - O2
transport and energy conversion in biological
systems Electronic effects in atom transfer
reactions - Metal-organic complexes
(metalloprotein mimics) allow atom transfer
reactions which with pure organics may be
forbidden - Applicable to organic and
biological reactions - Chiral recognition and
synthesis Structural analysis of siderophore,
ß-lactam and hydroxamic acid derivatives in
conjunction with all of the core
facilities Configuration and coordination

    ?-lactams, antibiotics, and anti-fungal and
    anti-tumor agents.
  • Elucidation and characterization of the dynamic
    structures of host/guest complexes, especially
    relatively large interlocked rotaxane molecules
