STOCKHOLM, Sept.13, 2012 /PRN=KYODO JBN/ --

    The Royal Swedish Academy of Sciences (RSAS) has awarded the Gregori

Aminoff Prize in Crystallography 2013 to:

    Carlo Gatti

    Institute of Molecular Sciences and Technology, Italian National Research

Council (CNR-ISTM)

    Milan, Italy

    and

    MarkSpackman

    University of Western Australia

    Crawley, Australia

    "for developing experimental and theoretical methods to study electron

density in crystals, and using them to determine molecular and crystalline

properties".

    Nature of crystals measured by X-rays and interpreted in Italy and Australia

    Crystallography is the science of the arrangement of atoms in solid

materials. To reveal the atomic structure of a crystal, an 'X-ray diffraction

method' may be used. In this method an X-ray beam strikes a crystal, showing a

diffraction pattern that, in turn, can be transformed into a 3D model of the

crystal. This technique is now widely used in geology, physics, chemistry,

biology, medicine and materials engineering. Purposes include determining

mineral properties, proteins and DNA structures, and developing strong new

materials.

    Both Carlo Gatti and Mark Spackman have independently developed concepts

for interpreting electron density distributions related to quantum chemistry

theory, using multipole analysis of high-quality X-ray diffraction data. This

approach has, in particular, significantly demonstrated and quantified the role

of hydrogen bonding in molecular systems. 'Charge density topology' is

important for classification of the type and strength of chemical bonding in

solid compounds and molecules.
