Chemical Sciences: A Manual for CSIR-UGC National Eligibility Test for Lectureship and JRF/Glossary

This is a glossary of Terms used in this book—an alphabetical listing of technical terms with the summaries of their effects. (Brackets "[]" are optional arguments and braces "{}" are required arguments.)

C

 * carbon-carbon bond
 * carbon-carbon bond forming reactions

F
Free induction decay

isotopologues
Isotopologues are molecules that differ only in their isotopic composition. Simply, the isotopologue of a chemical species has at least one atom with a different number of neutrons to the parent.

isotopomers
Isotopomers or isotopic isomers are isomers with isotopic atoms, having the same number of each isotopic atom but differing in their positions. It can be either constitutional isomers or stereoisomers. For example, CH3CHDCH3 and CH3CH2CH2D are a pair of constitutional isotopomers. (R)- and (S)-CH3CHDOH or (Z)- and (E)-CH3CH=CHD are examples of isotopic stereoisomers.

An isotopomer should not be confused with an isotopologue.
