The photoexcitation of (NO)2 at 242–221 nm is studied by photoion and photoelectron imaging. A broad and structureless absorption band starting at 41,300 300 cm 1 is observed. Ionization via the excited state accesses predominantly a dissociative state of (NO)2 . The broad kinetic energy distribution of the photoelectrons suggests that the excited state has a large valence component in the Fran...
