Chemical community

And last not least, we will have to see further improvements in the graphical user interfaces of software systems and the retrieval systems of databases in order to make software and databases more acceptable to the chemical community at large. Software and databases should speak the language a chemist is used to, with hand-drawn chemical structures and reaction equations, or even imderstand the spoken word - and only provide the desired information selectively, not buried in a phe of unnecessary output.

After World War II, the International Union of Chemistry became the International Union of Pure and Applied Chemistry (known in the chemical community as the lUPAC). Since 1949, the lUPAC has issued reports on chemical nomenclature on a regular basis. The most recent lUPAC rules for organic chemistry were published in 1993. The lUPAC rules often offer several different ways to name a single compound. Thus although it is true that no two com-... 

Cycloaddition reactions are close to the heart of many chemists - these reactions have fascinated the chemical community for generations. In a series of communications in the sixties. Woodward and Hoffmann [2] laid down the fundamental basis for the theoretical treatment of all concerted reactions. The basic principle enunciated was that reactions occur readily when there is congruence between the orbital symmetry characteristics of reactants and products, and only with difficulty when that congruence is absent - or to put it more succinctly, orbital symmetry is conserved in concerted reactions [3]. 

While still a student at the Academy, Ipatieffbegan to make a name for himself in the Russian chemical community as he began to publish some of his laboratory findings. His first professional milestone as a chemist came in 18h() when he joined Russia s Physical-Chemical Society. Here he came into close contact with Russia s most famous chemists, including Dimitri Mendeleev, discoverer of the periodic table and one of the founders ol the Society. In 1891, upon graduating from the school, he was appointed lecturer in chemistry at the Academy where he also continued to undertake original chemical research for his doctoral dissertation. In 1895, he was made assistant professor and, upon completion and acceptance of his dissertation in 1899, he became a full professor of chemistry. 

We should also note that 1UPAC changed their naming recommendations in 1993 to place the locant indicating the position of the double bond immediately before the -ene suffix rather than before the parent name but-2-ene rather than 2-butene, for instance. This change has not been widely accepted by the chemical community, however, so we ll stay with the older but more commonly used names. Be aware, though, that you may occasionally encounter the newer system. 

The red fox (Vulpes vulpes) uses a chemical communication system based on scent marks in urine. Recent work has shown one component of fox urine to be a sulfide. Mass spectral analysis of the pure scent-mark component shows M+ = 116. IR spectroscopy shows an intense band at 890 cm-1, and H NMR spectroscopy reveals the following peaks ... 

The number of explicit references to the periodic law to be found in late nineteenth-century journals is small and fluctuates irregularly. From these data alone it would be difficult to judge whether the periodic law was actually accepted by the entire chemical community or was merely an exotic concept, of interest only to a few specialists, (p, 600)... 

Mendeleev had personal reasons for indulging in hyperbole, of course, but the general response of the chemical community does indeed seem to have been that this accommodation of argon within Mendeleev s scheme was a major feather in its cap—no less major than any other empirical success, whether predictive in the temporally novel sense or not. 

I dedicate this book to Paul D. Bartlett, one of the grand pioneers of physical organic chemistry, who investigated perceptively several basic problems in organic chemistry at a time when the chemical community did not yet see their crucial aspects, for example, in the mechanism of the diazo coupling reaction (Wistar and Bartlett, 1941). I learned much from him when he invited me to attend his Friday seminars at Harvard University in 1951-1952.
