Enter a name for the first reactant. Select one of the six second reactants by clicking in the adjacent radio button. Finally click the submit button.
Wild card characters (*, % and _) are allowed in the name. The choice of any reactant as second reactant places no limit on the second reactant. Names of reactants that match the request will be listed on a page with the name as a link to the pages containing the data. If only one page matches the request, that page will be shown immediately.
Particular substances may be identified by any name that is in our database. Each is represented by at least one name, often more than one name. There is usually at least one systematic name which may also be inverted to bring one or more functional groups to the beginning of the name. Common names and often used abbreviations are also often included. Each name matching the request will be returned thus one reaction may be returned more than once.
Molecular formula have also been added as synonyms and may be searched. These are entered carbon first followed by hydrogen followed by other elements in alphabetic order (Hill order). Charge, + or -, is last if present followed by its numeric value if not 1. Examples: C6H6 (Benzene), C2H3O2- (Acetate ion), CO3-2 (rather than CO32-, Carbonate ion), C6H4ClNO2 (1-Chloro-2-nitrobenzene, 1-Chloro-3-nitrobenzene, etc.)
Capitalization is important as are numbers, italicized and other special parts. (However many names are also present as all lower case letters with all itallics, numbers, dashes, commas, etc. removed as a convenience in searching.) The names are entered into the database using the encoding scheme that has been used by the Radiation Chemistry Data Center for some years. Examples of names used are:
. [technical note: * will be converted to % as the character representing any number of any characters in an SQL search, _ represents a single occurrence of any character. The actual search will be executed by an Oracle DBMS. The requested search terms will be placed within single quote characters (') as part of the SQL search, thus if a term contains a single quote, or prime, two consecutive quote characters ('') must be used for each prime or single quote (e.g. 2,2''-Bipyridine). If one of the three wild card characters is present, the search requirement will use the term LIKE otherwise the operator will be = which requires an exact match.] The search should be faster if the first few characters are not wild card characters, however several characters as a fragment of a name starting and ending with * or % may be used. e.g. Methanol, Benzo*, %quinone% or _-Methylindole
Several of the pages contain links to additional information.
Some of the reactants are members of families such as acid-base pairs. If there is data for another reaction pair that differs only in that one of the reactants is a different member of such a family, a see also reference at the bottom of the page will show that reactant as a hyperlink to the data page for that reactant.The comments in some papers refer to a different paper that contains relevant data. The reference takes the form of an RCDC serial number, e.g. 94F095, or a squib, e.g. 91JUN/CHO. Either form will be in square brackets and serve as a hyperlink to the bibliographic reference.
