Abstract
From photoelectronic spectroscopy data N-amino-, N-dimethyl-, N-methylphenyl-, and N-methylformylamino-2,5-dimethylpyrrole molecules were found to have an acoplanar-oriented fragment conformation in the gas phase, while N-formylaniline had a planar structure. In aminopyrroles the n-n repulsion energy of unshared pairs exceeded the n-π* conjugation energy.
