A 1 + 1′multiphoton ionization (MPI) detection scheme for OH radicals is presented. The spectroscopic approach combines initial excitation on the well-characterized A2Σ+–X2Π band system with vacuum ultraviolet (VUV)ionization via autoionizing Rydberg states that converge on the OH+ A3Π ion state. Jet-cooled MPI spectra on the (1,0) and (2,0) bands show anomalous rotational line intensities, while initial excitation on the (0,0) band does not lead to detectable OH+ ions. The onset of ionization with the (1,0) band is attributed to an energetic threshold; the combined UV + VUVphoton energies are above the first member of the autoionizing (A3Π)nd Rydberg series. Comparison of the OH 1 + 1′ MPI signal with that from single photonVUVionization of NO indicates that the cross section for photoionization from OH A2Σ+, v ′ = 1 is on the order of 10−17 cm2.
