Archaeological waterlogged leathers dated from the 13th to 17th century have been analyzed using carbon-13 high-resolution solid-state nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR). The NMR and EPR spectra have been compared to modern vegetable-tanned leathers and crude hide. Both techniques allowed …

nuclear spins to equilibrate (what we now call "the spin-lattice relaxation time," T 1) was anyone's guess. Their best guess was a few hours, during which the sample had to sit, undisturbed, in the magnetic field. As Pound described it, "Ed agreed to come in around seven in the morning on Saturday and turn the magnet on and let it

Nuclear magnetic resonance or NMR is one of the most widely used discov-eries of Modern Physics. NMR is based on the bulk magnetic properties of materials made up of certain isotopes, most notably, protons (11H), but encompassing a wide variety of species including 13C, 19F, and 29Si. NMR is used to measure magnetic fields with exquisite …

Nuclear magnetic moments are of the order of a nuclear magneton. μ N = eℏ 2M = 5.051 ×10−27JT−1 (14.7) (14.7) μ → N = e ℏ 2 M = 5.051 × 10 − 27 J T − 1. where M is the mass of the proton. The nuclear magneton is smaller than the Bohr magneton by a factor m/M ≈ 1836. Table 1: Some common nuclei in NMR spectroscopy.
