HauptbeschreibungWritten by a founding father of computational chemistry, Structure and Properties of Organic Molecules provides organic, physical, computational, pharmaceutical/medicinal, and polymer chemists with a strong understanding of the structure and properties of organic molecules by bringing together the computational methods and the experimental methods commonly used for studies of molecular structure. Both a useful text and self-teaching guide, coverage includes experimental structures from electron, neutron, X-ray diffraction, microwave spectroscopy, and computational structures, ab initio, semi-emperitcal molecular orbital, and molecular mechanics calculations.
