The solvent accessible reduced carbon atoms in a molecule of interest are labeled with heavy hydrogen. The carbon atoms are labeled under anaerobic, aqueous conditions by exposing the molecule of interest to a hydrogen atom abstractor in the presence of a heavy hydrogen source and a heavy hydrogen donor. If the hydrogen atom abstractor is hydroxyl radical, an electron scavenger source is provided. Optionally, an internal reference is provided to facilitate experimental reproducibility.
