Abstract

Photoelectron spectroscopic investigations indicate that (i) monocyclic diaziridines prefer a trans‐conformation of the nitrogen‐lone pairs, and (ii) the interaction between these is comparable to that exhibited by open‐chain analogues, i.e. alkyl‐substituted hydrazines. The chemical experience concerning the particular case of NHNH→NN oxidation of diaziridines can therefore not be accounted for by a prevailing unfavorable ‘lone pair’ interaction. Thermochemical as well as entropy arguments may serve as an explanation. A rather unsatisfactory agreement between predictions from various theoretical procedures and experimental results for the ionization potentials of ‘lone pair’ MO electrons is noted.

Noncentrosymmetric (NCS) oxides exhibit a variety of technologically important properties including ferroelectricity, piezoelectricity, pyroelectricity, and second-order nonlinear optical behavior. [1][2][3] The rational design of new NCS materials, however, remains a challenge, although a number of
