Abstract

CO molecules in their electronic and vibrational ground state were state selectively detected using a tunable ArF excimer laser. Rotational state selectivity is due to the one‐photon resonance of the spin‐forbidden a ³Π, v’=2←X ¹∑⁺,v‘=0 transition. Subsequent absorption of two additional ArF laser photons yields, via a dissociative continuum, electronically excited C(3 ¹P) atoms, whose fluorescence is detected.
