Preferred Label : primary isotope effect;
IUPAC definition : A kinetic isotope effect attributable to isotopic substitution of an atom to which
a bond is made or broken in the rate-controlling step or in a pre-equilibrium step
of a specified reaction. The corresponding isotope effect on the equilibrium constant
of a reaction in which one or more bonds to isotopic atoms are broken, is called a
'primary equilibrium isotope effect'.;
