NMR spectroscopy

NMR spectroscopy is used for measurement of molecular and supra-molecular structure in solution state and solid state, relaxation time measurement to characterize molecular dynamics. Examples are: 2H pore-size measurements and 13C measurements of cellulose fibril aggregate thickness in both wet and dry solid samples.
