configurationally

Enantiopure oxaziridines where stereochemistry is entirely due to configurationally stable nitrogen are reported.

Some oxaziridines have the unique property of configurationally stable nitrogen atoms at room temperature due to an inversion barrier of 24 to 31 kcal/mol.

A graft polymer molecule is a branched polymer molecule in which one or more the side chains are different, structurally or configurationally, from the main chain.
