Chemistry Citation Index

Chemistry Citation Index Institute of Scientific Information, Inc. 

The Institute for Scientific Information (ISI), besides publishing Current Contents (p. 1611) and the Science Citation Index (p. 1637), also publishes Index Chemicus (formerly called Current Abstracts of Chemistry and Index Chemicus). This publication, begun in 1960 and appearing weekly, is devoted to printing structural formulas of all new compounds appearing in more than 100 journals, along with equations to show how they were synthesized and an author s summary of the work. Each issue contains five indexes author. 

H. H. Jaffe (1919-1989)297 was professor of chemistry at the University of Cincinnati. His research interests were quantum chemistry, the basicity of weak bases, spectroscopy, excited state chemistry, and the Hammett equation, of which he wrote a comprehensive review article in 1953.298 At one time, according to Science Citation Index, this was the most cited article in the chemical literature. 

There are many topics (such as searching chemical literature, Current Contents, or Citation Index the choice of hardware and maintaining the system use of statistical packages, etc.) that could be included into the book, but at some point a selection of what are the most common, and at the same time the most important, aspects of PCs in chemistry must be made. After all, the readers will judge if too many vital topics were omitted or not. 

Science Citation Index (SCI) is a combination of three indexes which provide coverage of all the important publications in the physical sciences. SCI is published every two months and is cumulated annually. There are cumulative indexes covering the period 1945-1979. It includes coverage of all of the major chemistry journals.

Databases. Sites such as Bath Information and Data Services (BIDS) and web of Science (WOS) provide access to abstracts of recent publications use these to find relevant literature for specific topics. Access is via the websites at http //www.bids.ac.uk/ or http //www.webofscience.com you will need a username and password - check with your department or library. In the case of BIDS, it provides access to databases covering subjects from science, engineering and medicine to economics, politics, education and the arts. Specific databases offered include ISI citation indexes EMBASE (international biomedical information) INSPEC (physics, electronic engineering and computing) international bibliography of the social sciences (IBSS) The Royal Society of Chemistry databases and education databases. See also Table 46.2. 

I don t look at the Citation Index, although in the back of my mind it s of course a nice feeling. But what I d really like to see is that NMR becomes even more useful. I d like to do things for the field, for chemistry, and for biomedical research in particular. 

The complex role of surface chemistry in the adsorption of aromatics has been highlighted and (we hope) clarified in Section IV.B. The seed for the explanations offered there had been planted as early as 1968-1971 in a series of landmark papers by Coughlin and coworkers [450,331,332] and Mattson and coworkers [24,6]. In hindsight, however, it is obvious that the arguments presented in these two series of papers cannot both be correct. Here we quote the critical statements in the key papers and follow their fate with the help of the Science Citation Index. The statistics of their citations are summarized in Table 39. 

Wentworth has been a member of the American Chemical Society, the American Solar Energy Society, and Alpha Chi Sigma. He has published over 125 papers, written three textbooks, and received numerous patents. One of the publications from his doctoral dissertation was selected as a pioneer paper in analytical chemistry. His papers on the chemical applications of nonlinear least squares became Citation Index Classics. His patent for pulse discharge ionization detectors was selected as one of the 100 most significant inventions of 1997. He retired after four decades of teaching and research, having about forty graduate students, half of whom received doctorates. The Robert A. Welch Foundation supported his efforts every year. 

A citation classic is a highly cited publication as identified by the Science Citation Index (SCI). Each scientific discipline has its own publication and citation rates. Most fields require at least 400 citations before a paper becomes a citation classic, but papers in smaller fields qualify with as few as 100 citations. However, as we have seen in Table 1, computational chemistry papers rank competitively with those of any other field of chemistry. 

FIGURE II. I Annual number of scientific papers in the Science Citation Index with (evolution OR phylogen ) and (development OR embryo ) in the title. The general trend is for a steady increase in research output post-1990.The figures are crude estimates of research activity because many studies omit these terms from the title, while a minority of papers with these terms actually deal with unrelated topics (e.g., computing, chemistry, sedimentology).

About 25 % of Jensen s papers deal with problems in coordination chemistry. An examination of the "Science Citation Index" shows that even today Jensen s production has an annual score of about 100 citations. 25 of these are to his early papers in ZeitscMftfur anorganische und allgemeine Chemie, Considering the statistical fact that the citation rate of an average paper is 1.7, culminating a few years after the appearance, Jensen s unusually high score is a testimony to the importance of his worlc... 

In addition to general abstracts such as Chemical Abstracts, Beilstein, and Science Citation Index, as well as computerized reference sources, such as CAS on Line, Sci-Finder, and Web of Science, the following general reference sources contain references, discussions, and other information pertaining to organopalladium chemistry. Their aCTonyms and abbreviations are shown and may be used throughout this Handbook. Many of these reference sources, such as Comp. Org. Synth, and Houben-Weyl, contain independent reviews, and those reviews that are pertinent to the Handbook are separately listed in the list of reviews (Sect. R.3). 

Figure 8 Frequency of citation of several popular computational chemistry methods based on data from Citation Index, which is published by die Institute of Scientific Information, Philadelphia, Pennsylvania. Use of MINDO/3 leveled off after MNDO appeared. As more users become aware of the advantages of AMI and PM3, diese methods are expected to displace the dder ones. It is curious, however, to see how long it takes users to switch to the newer, better mediods.
