It is amazing. Authoritative book!!! http://www.organic-chemistry.org/ ( Name reactions and graphical list - very useful and for all synthetic organic chemists) - http://www.ux1.eiu.edu/~cfthb/links/research/ (Links for researchers in Organic synthesis; superb site) http://www.organicworldwide.net/ (Organic chemistry sources worldwide)

This is a large version of the periodic table . It contains the name, symbol, atomic number, and mean atomic mass value for the natural isotopic composition of each element. The periodic table of the chemical elements is a tabular method of displaying the chemical elements . Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869.

Journal of Cheminformatics has published the meeting abstracts from the 8th German Conference on Chemoinformatics , which took place in Goslar, Germany last November. Journal of Cheminformatics is the official publishing partner of the conference, and the 2012 meeting represents the fourth consecutive year that the journal has been involved and the sixth year that Chemistry Central has been involved.
Lysergic acid diethylamide , commonly called LSD , or LSD-25 , is a semisynthetic psychedelic drug . The short form LSD comes from " L yserg s äure d iethylamid". A typical single dose of LSD during the 1960s was between 100 and 200 micrograms, a tiny amount roughly equal to one-tenth the weight of a grain of sand. Today, a typical single dose of LSD can be as low as 25–50 micrograms, although they are more commonly 50–100 micrograms. Threshold effects can be felt with as little as 20 micrograms. The effects of LSD can vary greatly, depending on factors such as previous experiences, state of mind and environment, as well as dose strength.

Unlike chemistry textbooks printed on paper, this webbook is able to contain dynamic Synthlet and Database pages that explore and make predictions about aspects of chemical structure & reactivity. Thanks go to the authors of web sites linked to from these pages, to members of the International Society for the Philosophy of Chemistry ( ISPC ) and to the members of the ChemEd internet discussion list who have answered my many questions and synthesized such interesting postings. This web book is being continually updated.

Josiah Willard Gibbs (February 11, 1839 – April 28, 1903) was an American scientist who made important theoretical contributions to physics, chemistry, and mathematics. His work on the applications of thermodynamics was instrumental in transforming physical chemistry into a rigorous deductive science. Together with James Clerk Maxwell and Ludwig Boltzmann , he created statistical mechanics (a term that he coined), explaining the laws of thermodynamics as consequences of the statistical properties of large ensembles of particles.
