Search for Species Data by Acidity Value

Please follow the steps below to conduct your search (Help):

Rules for values (step 1) (Back to search)

• You may search for species based on acidity values in two ways:
  1. Specify a single value; the system will search for values within 5.0 kJ/mol (1.2 kcal/mol) of this value.
  2. Specify a range. The limits of the range should be separated by a comma.
• The units used for displaying data will be the same ones used to specify the value.

Rules for formula restriction (step 2) (Back to search)

A chemical formula may be entered to restrict the search to species which match the formula. The manner in which the formula is interpreted is controlled by two checkboxes below the formula entry box:

Allow elements not specified in formula

When checked, this option indicates that species containing elements not specified in the formula will also be matched. For example, a search for C2 will match all of the species which contain exactly two carbon atoms and any number of other atoms.

Allow more atoms of elements in formula than specified

This option indicates that species containg more atoms than specified of a given element will be matched. For example, a search for HC with only this option checked will match only hydrocarbons.

Rules for data types (step 4) (Back to search)

• If one or more of the data types are checked, the search will be restricted to species which contain at least one of the data types specified.
• If none of the data types are checked, there will be no restrictions on the search.
