Selectively excited x-ray emission spectra of N2

• Resonant and non-resonant X-ray emission spectra of N-2 are presented. The role of the parity selection rule in the case of homonuclear diatomic molecules is discussed thoroughly and illustrated by the X-ray emission spectra. We also discuss how the parity selection rule and the angular anisotropy of the resonant X-ray emission may affect intensities in a fluorescence yield measurement of N-2. Simulated vibrational band profiles calculated using the lifetime-vibrational interference formula are found to be in excellent agreement with the experimental emission bands.
