Secondary equilibrium isotope effects

Verify that a decrease in H—C (D—C) vibrational frequency on dissociation will cause the observed secondary equilibrium isotope effect KH/KD > 1 for dissociation of HCOOH (DCOOH). [Pg.112]

This chapter is a review of secondary equilibrium isotope effects (IEs) on acidity, primarily on the comparison of protium with deuterium (and also tritium), but also addressing the IEs of 13C, 14C, 15N, and lsO. Secondary IEs are those where the bond to the isotope remains intact, whereas primary IEs are those where the bond is broken. Primary isotope effects are generally... [Pg.123]
