Doctoral dissertation, Harvard University.http://dissertations.umi.com/gsas.harvard:11628http://nrs.harvard.edu/urn-3:HUL.InstRepos:12274612Nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) are techniques widely utilized by many scientific fields, but their applications are often limited by short spin relaxation times and low sensitivity. This thesis explores two novel forms of NMR addressing these issues: nuclear spin singlet states for extending spin polarization lifetime and nitrogen-vacancy centers for sensing small samples.en-USChemistryQuantum physicsAtomic physicsmagnetic resonancenitrogen vacancyquantum filtersinglet statespin lockThesis or Dissertation2015-06-04
