The radiative lifetimes of NO+ (X 1Σ+, v=1, 2 and 3) have been measured in a new Fourier transform ion cyclotron resonance (FT/ICR) apparatus using the monitor ion technique. Resonance-enhanced multiphoton ionization (REMPI) via the C 2Π Rydberg state of NO was used to prepare vibrationally state-selected NO+ (X, v). Photoelectron spectroscopy experiments indicate v=2 was formed with greater than 97% purity and v=3 with greater than 91% purity, consistent with literature values of Miller and Compton which indicate good vibrational selection for v=0 and v=1. The radiative lifetimes of the NO+ (X) v=1, 2 and 3 vibrational states were measured to be 90, 32 and 16 ms, respectively. Comparison is made with theory and other experiments where available.
