ismers

Ismers refers to a term that does not have a widely recognized, standalone meaning in mainstream reference works. In most English-language contexts, what is more commonly intended is the word “isomer” or its plural “isomers.” As a result, “ismers” is typically treated as a misspelling or nonstandard variant rather than a distinct concept.

In chemistry, isomerism describes the phenomenon where two or more compounds share the same molecular formula but differ in the arrangement of atoms or in spatial orientation. Major classes include constitutional (structural) isomers, and various forms of stereoisomerism such as enantiomers and diastereomers, as well as geometric (cis/trans) isomers. The established terminology distinguishes these categories; there is no formal category known as “ismers.”

Usage notes and interpretation:

- If a source uses “ismers,” it is prudent to check whether the author intended “isomers.” The context will usually reveal whether the term refers to chemical isomers or to something else.

- In non-scientific or fictional writings, “ismers” could be coined as a neologism or as a proper name within a worldbuilding context. Such uses should be clearly defined within that work.

There are no standard references that define “ismers” as a separate scientific term. If you have a specific text or context where the word appears, that context would determine whether it is a simple misspelling or a deliberate, nonstandard usage.
