Abstract
We implemented a straightforward algorithm for generating a list of potential molecular fragments from a given molecule by simulating sequential fracturing of single bonds; we refer to this approach as the Simulated Sequential Single-Bond-Breaking (3S2B) algorithm. Applying the algorithm to a list of chemical structures, we generated a searchable database of molecular fragments. In this article, we describe the 3S2B algorithm and demonstrate three uses for the molecular fragment database: (i) to propose possible molecular structures for a given high (or low)-resolution mass value, (ii) to evaluate the quality of measured mass spectra for known compounds, and (iii) to propose possible identities for mass spectra of unknown compounds without a reference mass spectral database. An implementation of the 3S2B algorithm and command line interface for working with the molecular fragment database is available: https://github.com/EightBitAdder/3S2B-CLI.
期刊介绍:
The Journal of the American Society for Mass Spectrometry presents research papers covering all aspects of mass spectrometry, incorporating coverage of fields of scientific inquiry in which mass spectrometry can play a role.
Comprehensive in scope, the journal publishes papers on both fundamentals and applications of mass spectrometry. Fundamental subjects include instrumentation principles, design, and demonstration, structures and chemical properties of gas-phase ions, studies of thermodynamic properties, ion spectroscopy, chemical kinetics, mechanisms of ionization, theories of ion fragmentation, cluster ions, and potential energy surfaces. In addition to full papers, the journal offers Communications, Application Notes, and Accounts and Perspectives
