- Abstract
- Two-photon absorption spectra of the CO [equation] transitions have been observed in a room temperature cell and in atmospheric pressure hydrocarbon flame using fluorescence [equation] and ionization detection. The ratio of the transition strengths for the [equation] branch head is found to exceed 200:1 for excitation with two identical linearly polarized photons compared with two circularly polarized photons.
