has been reformatted by Knovel to provide easier navigation vii Introduction This is a book that I wrote for myself It was started 16 years ago when my duties began to include the origination of ultraviolet spectrophotometric testing methods for products of interest to my company Painful and wasteful experiences of rediscovering someone else's analytical procedures soon led to my keeping notebooks and card files of published UV methods Many times since, these files have enabled me to avoid conducting lengthy experiments or making tedious literature searches When I decided to share them with others, I greatly expanded their scope to include clinical, biochemical, and pharmacological analysis, as well as other topics not normally part of either my responsibility or my interests This volume consists of more than 1600 references to analyses accomplished using UV absorption measurements, arranged alphabetically by senior author The book is compound-oriented; that is, it deals with materials, and most papers dealing primarily with instrumentation and techniques have been excluded Some of these items merely mention the subject treated Others are abstracts containing enough detail to permit use of the method without consulting the original article This book is intended, however, not merely to inform the reader and to grant him rapid access to the available literature, but to stimulate creativity by a quick review of the approaches others have taken to a problem similar to his own In this work, "UV" refers to the region 180-380 nm; occasional excursions outside these limits in either direction will be made without explanation or apology Fluorescence measurements are not included With but few exceptions, neither are photometric titrations or measurements made with nondispersive photometers The index is arranged by substance analyzed and substance determined Its lavish use of cross-referencing to trivial or generic names should help analysts having limited knowledge of organic chemical nomenclature Although a great debt is owed to the various abstract journals (particularly for many of the foreign language references), to save space only the pri- mary journal citations are given In general, these cover the period from 1940 through 1964 Although more than 265 different sources were used, coverage is neither comprehensive nor uniform Emphasis was placed on readily available English-language journals Two conventions are followed which will be new to some readers: The abbreviation nm (nanometer) is used instead of niM (millimicron) This is not a radical innovation Certain British and European journals have adopted it and it has been used in some recent publications by the U S National Bureau of Standards My intent is, obviously, to promote the elimination of a frequently used Greek letter which annoys thousands of technical typists and which has led to the use of such abominations as mu and mmu To save space, the ASTM CODEN are used for journal citations The CODEN are four-letter abbreviations for titles Originally proposed by Dr Charles Bishop, they were finally implemented by Dr L E Kuentzel and the Wyandotte-ASTM Punched Card Project Each CODEN citation is followed by volume number, initial page number, and the final two digits of the year of publication Hence, Appl Spectry , 18, 158 (1964) becomes APSP-18-158-64 When the year of publication is the only appropriate temporal citation, it appears first, e.g , CHIN-1962-1501 Should a single item cover separate papers by the same author (s) in the same volume of the same journal, the two page citations are separated by a comma, as ARKE-11-129, 151-57 If the number of the journal is thought to be needed, it is placed in parentheses after the volume (or year) listing KTTM-1959(12)-46 The key to the CODEN used follows this introduction and is presented with the kind permission of the American Society for Testing and Materials Others have also been kind and particular thanks are due my employer, National Aniline Division of Allied Chemical Corp., whose library at Buffalo was my mainstay, and my wife, Ann, who did some of the tedious chores that the writing of this sort of book engenders R G W Orchard Park, N Y ,February, 1965 Key to CODEN The following CODEN are taken from the ASTM CODEN FOR PERIODICAL TITLES, STP 329, * and are reprinted with
