One of the most remarkable phenomena of chemistry is that of isomerism.
Among organisms we sometimes observe a phenomenon which looks very like isomerism.
A rough illustration of the phenomenon of isomerism is furnished by written language.
Further, the allotropic modifications of elements and the isomerism of compounds increased the difficulties.
A further distinction is necessary to a survey of the subdivisions of isomerism regarded in its widest sense.
A general philosophical interest is attached to the phenomena of isomerism.
Before entering into detail it may be useful to consider the nature of isomerism from a general standpoint.
isomerism i·som·er·ism (ī-sŏm'ə-rĭz'əm)
The phenomenon of the existence of isomers.
The complex of chemical and physical phenomena characteristic of or attributable to isomers.
The state or condition of being an isomer.
