No2 resonance.

The unimolecular decomposition of expansion-cooled NO2 at excess energies 0−3000 cm-1 is described with emphasis on the manifestations of overlapping resonances. When NO2 is excited to energies above dissociation threshold, overlapping resonances interfere and give rise to final state-selected spectra which depend on the monitored final state of the NO product.Category 2: NO2, CN, SO3H, CHO, COR, CO2H, CONH2 Because of the full or partial positive charge on the element directly attached to the ring for each of these groups, they all have a moderate to strong electron-withdrawing inductive effect, -I: Fig. 1 They also exhibit electron-withdrawing resonance effects, -Re:Draw the Lewis structure for NO2⁻ including any valid resonance structures.
