Brit.

/ˌnɒnstɔɪkɪˈɒmᵻtri/, U.S.

/ˈˌnɑnˌstɔɪkiˈɑmətri/

Origin: Formed within English, by derivation. Etymons: non- prefix, stoichiometry , stoicheiometry n.

Etymology: < non- prefix + stoichiometry, variant of stoicheiometry n. Compare slightly earlier non-stoichiometric adj.

Chemistry.

The property of being non-stoichiometric; an instance of this.
