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

I

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 .
