Isotopic substitution can modify the rate of reaction in a variety of ways.
2.
Isotopic substitution is invaluable when using this approach to the determination of molecular structure.
3.
Isotopic substitution of D will alter k 1 and k 2 while not affecting k 3.
4.
The goal of spin labeling is somewhat similar to that of isotopic substitution in NMR spectroscopy.
5.
He also applied this knowledge to the effects of isotopic substitution on the reactivity of organic molecules.
6.
Therefore, large amounts of the less common isotopic species must be available, limiting observable solvent isotope effects to isotopic substitutions involving hydrogen.
7.
Isotopic substitution of one of two deuterium atoms for a hydrogen atom causes the environment of nearby NMR-active atoms to change dramatically.
8.
In addition, we have not specified the isotopic substitution in the N2 product of the second and third reactions because N2 is symmetric.
9.
Where _ a is the number of tracer atoms within S, while ^ b is the number of isotopic substitutions in the same molecule.
10.
Alternatively, it may mean that the isotopic substitution is at the reaction site, but vibrational changes associated with bonds to this atom occur after the rate-determining step.
