                        AROMATICITY and ANTIAROMATICITY
                       Electronic and Structural Aspects
                   by V. Minkin, M. Glukhovtsev & B. Simkin
 The concept of aromaticity is vital in theoretical chemistry.  Its versatility
 and usefulness for the systematization and prediction of peculiarities of
 structure and reactivity of organic compounds are well proven.  Recent years
 have seen a virtual explosion in the development of various criteria of
 aromaticity and in theoretical work aimed at gaining a deeper insight into the
 origins of this phenomenon.
 This work critically analyzes the different approaches to the quantitative
 description of aromaticity, according to principal physical criteria, scope and
 limitations.  Unlike earlier works on the subject, AROMATICITY and
 ANTIAROMATICITY emphasizes the role modern THEORETICAL and COMPUTIONAL chemistry
 has played in the development of the concept and
 its expansion into new branches of chemistry such as ORGANOMETALLIC
 and CLUSTER structures, compounds withTHREE-DIMENSIONAL structures and SATURATED
 compounds.
 Written for specialists and graduate students in PHYSICAL, ORGANIC and
 ORGANOMETALLIC chemistry, this work clarifies definitions, criteria,
  theoretical background and recent development and applications.  The book...
         Helps chemists integrate the results of calculations on molecules
         and ions into the general body of chemical knowledge
         Includes important experimental observations on aromatic structures and
         behavior
         Provides an extensive bibliography covering the literature up through
         1992 and end-of chapter references, presenting readers with all the
         sources necessary for further research.
