This volume opens with an overview of tautomeric equilibria involving substituents (such as OH, NH2j SH) in six-membered heterocycles provided by B. Stanovnik and M. Tisler (University of Ljubljana, Slovenia) together with O. Denisko (CAS, Columbus, Ohio) and your editor. The chapters update reviews which appeared in earlier volumes of this series and brings this complex and important subject up to date.

In addition to the two letters of "espucci, the present volume contains the evidence taken in the Columbus lawsuit bearing on the subject, the chapters in the history of Las Casas in which the veracity of Vespucci is discussed, the narrative of the voyage of Hojeda from Navarrete, and some other documents throwing light on the career of the Florentine adventurer. 

H + CH2 CH3 This reaction has been the subject of several experimental [11] and theoretical studies [12]. The published theoretical work calculated portions of the hindered rotation barriers for different values of Rh-C Ihe distance of the attacking H from CH2. This calculation employed a tzp basis set [13] with an multireference singles and doubles configuration interaction (MRSDCI) wavefunction and was carried out with the COLUMBUS program system [14]. This work has now been supplemented by a much more extensive mapping of the hindered rotational potential with a less expensive dzp basis set [13], Tests show that Vtr is not sensitive to dzp or tzp basis set selection. 

The reader will find simple applications of group theory in Chapters 10 and 15. A non-mathematical introduction to the subject is given in Symmetry and Structure by S. F. A. Kettle, Wiley, Chichester and New York, 1995. Also relevant, useful and/or relatively non-mathematical are Symmetry in Coordination Chemistry by J. P. Fackler Jr., Academic Press, New York, 1965 Symmetry in Chemistry by H. H. Jaffe and M. Orchin, Wiley, New York, 1965 Molecular Symmetry and Group Theory by A. Vincent, Wiley, London, 1977 Symmetry in Chemical Bonding and Structure by W. E. Hatfield and W. E. Parker, Merrill, Columbus, Ohio, 1974 and Group Theory for Chemists by G. Davidson, Macmillan, London, 1991. More mathematical is Chemical Applications of Group Theory by F. A. Cotton, Wiley, New York, 1990. 

STN International Scientific Technical Network, computer system which is jointly offered by three database producers the American Chemical Society, -y FIZ Karlsruhe and the Japan Information Center of Science and Technology (JICST). The three service centers at CAS in Columbus (USA), in Karlsruhe (Germany) and in Tokyo are linked via satellite and submarine cable. STN currently offers about 160 databases in a variety of scientific and technical subject areas.
