Versatile NMR NMR is a science which is used to study chemical composition using 1 D and 2 D structures and will replace x-ray crystallography . Time domain NMR spectroscopic techniques are used to probe molecular dynamics in solutions. Solid state NMR spectroscopy is used to determine the molecular structure of solids.MRI, which is based on NMR, is extensively used in medicine.
