not having isomers
Etymology
'nonisomerous' is formed in Modern English by the prefix 'non-' + 'isomerous', where 'non-' meant 'not' and 'isomerous' derives from Greek 'isomeros' meaning 'equal parts'.
'isomerous' comes from Greek 'isomeros' via New Latin 'isomerus' and 19th-century scientific English 'isomerous'; the adjective 'nonisomerous' was later formed by adding the negative prefix 'non-'.
Initially 'isomeros' meant 'equal parts' in Greek; over time it came to be used in scientific contexts for molecules having the same composition but different arrangements (isomers), and 'nonisomerous' now means 'not exhibiting isomers'.
