text: The database can be searched by entering one or more of the following parameters: chemical name (is possible to request partial or full matching), molecular formula, number of different types of atoms present in the molecule (as a single value or as a range of values), molecular weight (as a single value or as a range of values), CAS Registry Number or SDBS number. In all cases “%” or “*” can be used as wildcards. The result of the search includes all the available spectra for the search parameters entered. Results can be sorted by molecular weight, number of carbons or SDBS number in ascending or descending order.
