The results list shows the found compounds, their molecular weights, and their difference in mass from the target value, denoted "dm". If an elemental symbol such as Fe or Na was entered for a custom element, the program will use that symbol in the results list. This is so that C2_ 5 can represent five custom 2 atoms, while C 2 represents two carbon atoms. If you used a custom element and typed a weight for it, it will be notated in the results list by C1_, C2_, C3_, etc. Selecting calculate will instruct the program to find all of the compounds that match the specifications. Fe, Pb, Na), or a valid abbreviation (eg.

Clicking one of the Custom boxes brings up the typical Min and Max boxes, plus a box where you may type a weight for the custom element, an elemental symbol for one of the valid elements (eg. boxes are used to enter custom elements or abbreviations besides the ones listed. For Thorough Searching the minimum and maximum are automatically determined based on the target weight and the weight of the elements. These boxes specify the minimum and maximum number of times the element may appear in the empirical formula of the compounds.

If Bounded Searching is on (see below), the Min and Max boxes appear once an element is selected. You specify which elements a compound contains by clicking the boxes next to the element names. Setting a tolerance in parts per million will change the difference in mass results (dm=) to also be shown in parts per million. The tolerance can also be specified in Parts per Million (Ppm) by checking the Ppm Mode option. 1 in the tolerance box will find compounds whose weights lie between 77.9 and 78.1. For example, typing 78 in the weight box and. The tolerance defines what range of compounds to match. Set the weight tolerance to an acceptable value. Type a weight in the Molecular Weight of Target Compound box. Select the Match Molecular Weight radio button Matching Molecular Weightsįor finding compounds based on molecular weight: This is useful for finding possible compounds based on data, simply the reverse of what the main program does.

The Formula Finder can be used to find empirical formulas of compounds that have a specific molecular weight or specific percent composition data.
