✦ Synopsis

The Nls and 01s regions of gaseous N,N-dimethyl-p-nitroaniline have been studied by X-ray photoelectron spectroscopy. The Nls (-NO*) peak is z 0.5 eV broader than the Nls (-NH,) peak, indicating the presence of intense, unresolved shake-up. A shake-up peak has been observed in the 01s region at 2.1 eV higher binding energy than the main peak, with a relative intensity of 50%. The results have been compared with the corresponding features in the paranitroaniline and in the solid, and it has been found that the 01s shake-up intensity remains essentially unchanged while the Nls shake-up is enhanced in going to the solid. Comparison has also been made with a CNDOlS CI calculation which somewhat underestimates the relative intensities but is in good overall agreement with experiment.
