The recommendations described here adhere to established practice as closely as possible, in particular to IUPAC and IUBMB recommendations and to "best practice" in the PDB, especially to its atom labelling of amino acids, and particularly to Cahn-Ingold-Prelog rules for stereochemical nomenclature. ...
generally. As such, these outsized elements are fleeting, lasting mere milliseconds before decaying into lighter elements, according to the IUPAC. For instance
because of thedouble bond, carbon “b” is treatedas ifit is connected totwo oxygens. The same rule is applied for any other double or triple bond. So, when you see a double bond count
Elements X and Y have atomic numbers 37 and 52 respectively. a. Write the electronic configuration of X and Y. b. Use the configuration to identify the group and period of X and Y in the IUPAC periodic table. c. Which of the two ...
Your chemistry should look like typeset chemistry. Refer to the standards of the American Chemical Society or the IUPAC. Looking at some published books or journal articles may also help you in arranging long or complicated equations, structures, or reaction schemes. ...
Marcus Sitzmann from NCI discussed how InChI/InChIKeys are used within the NCI Chemical Identifier Resolver to annotate more than 80M unique chemical structures. Daniel Lowe from NextMove Software addressed features in IUPAC nomenclature that cannot be addressed by standard InChI such as accurate repre...
When Diels and Alder originally discovered this phenomenon, they assigned the name “endo” to the major product (where the dienophile is pointing “in”, towards the alkene) , and the term “exo” (outside, such as in “exoskeleton”) to refer to the minor product (where...
There appears to be no common ground with nomenclature used in computational work or in NMR. The recommendations described herein adhere to established practice as closely as possible, in particular to IUPAC and IUBMB recommendations, and to "best practice" in the PDB, especially to its atom ...
