WebChloroform-d (deuterochloroform, CDCl 3) is a deuterated NMR solvent. It is an anhydrous solvent, which minimizes any interference from water peaks. It is useful in performing critical air- and moisture-sensitive NMR analysis. It may be synthesized by reacting trichloroacetophenone and sodium deuteroxide. [ 1] WebThe Automated Topology Builder (ATB) and Repository is intended to facilitate the development of molecular force fields for Molecular Dynamics or Monte Carlo simulations of biomolecular systems.
