The electronic structure of the title compound 1 has been investigated
by UV photoelectron spectroscopy and quantum chemical calculations. 1
has two nearly degenerate n(N) lone-pair orbitals which form the two
highest occupied MOs. The third highest occupied MO is mainly localize
d at the oxygen atom (n(0)). All calculations indicate that the molecu
le has a twisted C-2 conformation.
