isomer 是什么意思

	n. 【化学】同分异构体；【物理学】同质异构素。 isomer of nucleus 原子核的同质异构素。 an optical isomer旋光异构体。

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

	1.	Can it be resolved into optical isomers ? 这能离析为旋光异构体吗？
	2.	Allene is an isomer of methyl acetylene . 丙二烯是甲基乙炔的一种异构体。
	3.	how many different isomers of octane 销 are there? 辛烷有多少种同分异构体？
	4.	Such molecules are known as enantiomorphs or optical isomers . 这种分子被称为对映结构体或旋光异物体。
	5.	They are said to be conformational isomers also called conformers . 它们叫做构象异构体，也叫做异象体。
	6.	Evidently, living things can somehow distinguish between optical isomers . 显然，生物体对这两种同分异构体能够有所识别。
	7.	Isomers are defined as compounds having the same formula but different structures . 异构体被定义为化学式相同而结构不同的化合物。
	8.	Substances which have identical molecular formulas but different structural formulas, are known as isomers . 凡具相同分子式但不同结构式的物质称为异构体。
	9.	The term "normal" applies to the isomer that has all its carbon atoms linked in a straight chain . 对这类异构体采用“正构”一词是因为这类异构体的全部炭原子都以直链形式连在一起。
	10.	The amino cyclohexylcarbinols(9) derived from the fused isxoazolidine(8) were a mixture of cis and trans isomers . 从稠合的四氢异唑（8）所得到的氨基环已基甲醇（9）则是顺式和反式异构体的混合物。
