Index Guide

The most important tool for the user of Chemical Abstracts is the Index Guide (Fig. 19). It is the indispensable key to the volume indexes and should be consulted before beginning any literature search. When starting a backfile search it is advisable to check whether an Index Guide exists for the questioned period (Sect. 2.1.4). This corresponding Index Guide should be consulted before using the indexes. 

The Index Guide is a work of reference providing cross-references to the various CA volume indexes. It is not itself an index as it does not refer directly to abstract numbers. It comprises an alphabetically ordered collection of subject terms, synonyms, acronyms, trivial and trade names, all concepts which are not used in the strictly controlled vocabulary of the indexes. For instance, an entry may refer to the corresponding systematic substance name as used in

The Chemical Abstracts System (CAS) produces a set of various databases ranging from bibliographic to chemical structure and reaction databases. All the databases originate from the printed media of Chemical Abstracts, which was first published in 1907 and is divided into different topics. Author index, general index, chemical structure index, formula index, and index guide arc entries to the corresponding database (Table 5-3). 

Quite naturally there is a certain amount of arbitrariness in this system, although the lUPAC nomenclature is followed. The preferred Chemical Abstracts index names for chemical substances have been, with very few exceptions, continued unchanged (since 1972) as set forth in the Ninth Collective Index Guide and in a journal article. Any revisions appear in the updated Index Guide new editions appear at 18-month intervals. Appendix VI is of particular interest to chemists. Reprints of the Appendix may be purchased from Chemical Abstracts Service, Marketing Division, P.O. Box 3012, Columbus, Ohio 43210. 

Several systems of nomenclature have been used for naphthalene, and many trivial and trade names are well estabUshed. The Chemicaly hstracts Index Guide is employed in this article. The numbering of the naphthalene nucleus is shown in (1) older practices are given in (2) and (3).

In this book we use the Nomenclature of Organic Chemistry of the International Union of Pure and Applied Chemistry, 1979 Edition ( Blue book , IUPAC, 1979), the Revised Nomenclature for Radicals, Ions, Radical Ions, and Related Species (IUPAC, 1993), and additional rules applied by the Chemical Abstracts Service for the 1987-1991 Index Guide Chemical Abstracts, 1992).

Part II consists entirely of systematic names of specific compounds according to Chemical Abstracts nomenclature (see the Index Guide in Chemical Abstracts, Volume 76, 1972). Each compound is listed under the parent name as it would appear in Chemical Abstracts, and each entry from Volumes 56 through 59 is followed by the registry number in brackets. Entries from Volumes 58 and 59 are, for the most part, taken from the appendices which follow the procedures. When the Chemical Abstracts name differs in Collective Indices 8 and 9, both names have been included. Some compounds in the appendices of this volume have been omitted from the index in accord with the guidelines given for Part I. 

In the foregoing the description of microresonators was limited to the index guiding type. Resonators with the same functionality can be implemented in PBG structures5. In these cases, with the high index contrast used, the cavity volume is even more reduced resulting in FSRs of 10 - 100 nm.

In general, as the variation of the temporal profile of the non-stationary light beam due to the SS effect or the second-order GVD effect is continuous, emission of radiation field from the guiding region is also continuous upon propagation of the pulse. This emission prevents formation of a spatiotemporal soliton in the step-index guiding structures.
