### Abstract

Measurement of mass-, energy-, and angle-resolved fragment ions reveals that the [Formula Presented] value for [Formula Presented] with kinetic energy [Formula Presented] is [Formula Presented] in the region of the [Formula Presented] excitation and that the [Formula Presented] value for [Formula Presented] with kinetic energy [Formula Presented] varies from [Formula Presented] to [Formula Presented] across the O [Formula Presented] resonance. These findings postulate that the [Formula Presented] molecule excited to the lower branch of the vibronically split O [Formula Presented] excited states deforms into a bent geometry while the molecule excited to the higher branch remains in a linear geometry.
