Abstract: A computer implemented system and method for determining the isotopic anatomy of molecules. The system receives a user identified molecule that is to be analyzed, makes an initial guess as to the isotopic anatomy of the molecule, and iteratively refines the initial guess based on one or more observations made by the user. When sufficient iterations have been performed, the system outputs information about the isotopic anatomy of the molecule. The information may then be stored, displayed on a monitor, analyzed for making other conclusions, and/or printed.
