## Abstract We used gravimetric analysis (GA) and ^13^C solidβstate nuclear magnetic resonance (NMR) to study solidβphase transition from the transparent single crystal of Lβserine (LβSer) monohydrate to a turbid powder. We found that LβSer monohydrate loses water molecules and transforms into an a
Carbon-13, deuterium and proton NMR line shapes of polycrystalline tert-butyl iodide (1) have been studied between 200 K and the melting point (239 K). Carbon-13 and deuterium spin-lattice relaxation times (T ) were measured between 313 and 200 K in the liquid and solid phases of 1. The NMR line sha
