Isotopolog ion
Ions that differ only in the isotopic composition of one or more of the constituent atoms.
Note 1: For example, CH4+ and CH3D+ or 10BF3+ and 11BF3+, or the ions forming an isotope cluster corresponding to the natural isotopic abundances of the constituent atoms.
Note 2: Isotopolog is an abbreviation of isotopic homolog.
