The products produced by photofragmentation in a molecular beam of sodium iodide, NaI, are investigated utilizing the technique of resonance ionization spectroscopy for the metal fragment, Na. Time‐of‐flight mass spectra are recorded, as a function of the wavelength of the resonant excitation step, and in dependence of the laser pulse energy. In particular, the appearance of non‐resonantly generated atomic and molecular ions is discussed, highlighting the importance of mass‐selective analysis of the ions formed in the interaction volume of the laser and molecular beams.
