isomer    音标拼音: ['ɑɪsəmɚ]
n. 异构体

异构体

isomer
n 1: a compound that exists in forms having different
arrangements of atoms but the same molecular weight

Isomer \I"so*mer\ ([imac]"s[-o]*m[~e]r), n. [See {Isomeric}.]
(Chem.)
A compound which is isomeric with another body or compound; a
compound having the same chemical composition as another
compound; a member of an isomeric series.
[1913 Webster PJC]

Note: An isomer may be a {structural isomer}, in which some
of the atoms are bonded to different atoms (as in
{CH3.CH2.NH2} and {CH3.NH.CH3}), or an {optical
isomer}, in which the number and types of chemical
bonds are identical, but the arrangement of the atoms
in three-dimensional space is different; the latter are
also called {stereoisomers}.
[PJC]

  • What Is an Isomer? Definition and Types - ScienceInsights
    Isomers are molecules that share the same chemical formula but have a distinct arrangement of atoms in space This subtle difference in atomic organization can lead to vastly different physical and chemical properties, as it dictates a molecule’s shape and how it interacts with other molecules
  • Isomerism | Definition, Types, Examples | Britannica
    isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties The roots of the word isomer are Greek— isos plus meros, or “equal parts ”
  • Isomerization - Wikipedia
    In chemistry, isomerization or isomerisation is the process in which a molecule, polyatomic ion or molecular fragment is transformed into an isomer with a different chemical structure [1]
