Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Chemistry, 1999.Includes bibliographical references.Several developments in solid state nuclear magnetic resonance (SSNMR) spectroscopy methods are presented. All studies are performed with magic angle spinning (MAS) and high-power proton decoupling, for optimal sensitivity and resolution. Chemical shift are assigned by multi-dimensional correlation spectroscopy in isotopically enriched molecules ...by Chad Michael Rienstra.Ph.D
