title: Resonance-enhanced multiphoton ionisation of purine.
abstract: State-of-the-art molecular-beam techniques reveal that the lowest lying electronic excited state in purine is the n pi* state. Using multiphoton ionization spectroscopy, the origin is found to occur at 31,309 cm(-1), and a vibrational structure is visible that is assigned to the skeletal motion of the ring (see figure).
