The purpose of this programming project is to assign automatically reasonable molecular formulas to experimental masses obtained from high-resolution mass spectra. The program developed reads experimental carbon-12 masses, converts them to corresponding Kendrick masses, and assigns a set of reasonable molecular formulas to each Kendrick mass within a given tolerance. The computational methods to do this are based on the tables previously developed by Guffey and Weber. The methods used to search these tables and generate the corresponding molecular formulas are discussed. This program is organized now so that it is resident on a disk pack on the IBM 370/158. Data entry may be from cards or from ket-to-disk data entry (TSO) terminal. This program is being used to process data acquired from the CEC 21-110B mass spectrometer. The development of this program will be continued to increase its analytical capabilities and to increase its ease of use. Acquisition of high-resolution mass spectral data for 12 fractions obtained from separation of a Canadian Tar Oil Sand sample has been continued.
