public class Isotopes
extends IsotopeFactory

List of isotopes. Data is taken from the Blue Obelisk Data Repository, version 10 (Willighagen, E. and Hutchinson, G. and Niehaus, C. and Buchwald, J. and Pfeiffer, M. and Leidert, D. and Brefort, J., Blue Obelisk Data Repository (version 10)). The data set is described in the first Blue Obelisk paper (Guha, R. et. al.. J. Chem. Inf. Model.. 2006. 46).

The isotopes.dat file that is used by this class is a binary class of this data, improving loading times over the BODR XML representation. It is created from the original BODR files using tools from the cdk-build-util repository.
