Action spectroscopy of highly excited molecular ions in molecular beams

• The use of action spectroscopy for quantitative comparisons of different parts of a recorded spectrumrequires that the efficiency of the emission process after photon absorption is quantitatively known. Thequantum yields of measured photo-dissociation processes after photo-absorption are derived here formolecular beams with broad energy distributions. The effect of radiative cooling on the yield is included.The quantum yield for both low energy photons and radiative species shows large variations with photonenergy.
