This index is a guide to organic compounds which have material constants of general interest described in the Landolt Bornstein New Series. Compiled are volumes containing molecular constants, density, surface tension, dielectric constants, refractive index, vapor pressure, phase transition, temperatures & transition enthalpies. In total, 16897 compounds with 33828 references to numerical data are recorded. All compounds are given with the drawing of the chemical structure, the molecular formula, chemical names, the Chemical Abstracts Registration numbers (CASRN) & references to all the Landolt Bornstein citations, including their use in binary mixtures. A general introduction explains the structure & the use of the index. Each volume contains a CD-ROM with the full content of the volumes & a program for structure research.

Volume IV/7 Liquid Crystals is devoted to critically selected and assessed fundamental data, mainly transition temperatures, which characterize the existing liquid crystalline phases and states of a large number of compounds. All relevant references including the very important patent literature and data (1850-1995) were collected in the data base LIQCRYST, from which the present Volume IV/7 has been derived by an individual critical choice of compounds, references and data. The printed tables offer an overall picture of the liquid crystalline field. Furthermore the comparison of corresponding data and perhaps the elucidation of structure-function relationships is facilitated, whereas the data base allows a facile access to any substructure and property search.
