The most common isotope of hydrogen is protium, an atom that consists of a proton or a proton and an electron. Because of a small amount of deuterium (one proton and one neutron) and tritium (one proton and two neutrons), the atomic mass of hydrogen is …
WebNormal KIEs for the deuterium effect are around 1 to 7 or 8. Large effects are seen because the percentage mass change between hydrogen and deuterium is great. Heavy atom isotope effects involve the substitution of carbon, oxygen, nitrogen, sulfur, and bromine, with effects that are much smaller and are usually between 1.02 and 1.10.
