A drift tube mass spectrometer coupled with ion laser and ion laser pumped tunable dye laser photon sources has been used to measure the thermal energy 300K photodissociation cross sections for two positive ion clusters, nitric oxide clustered with the nitric oxide ion and water clustered with the nitric oxide ion. Measurements were made spanning a photon wavelength range from 799 to 350 nm. The absolute photodissociation cross sections for nitric oxide clustered with the nitric oxide ion were found to vary smoothly with photon wavelength attaining a maximum value of 2 x 10-17 square centimeters at approx. 650 nm decreasing at both longer and shorter wavelengths. In addition, coupling of clustering reactions into the photodissociation cross section appeared under a variety of conditions. Photodissociation cross sections for water clustering with the nitric oxide ion were found to be small or zero. Upper limits of approx. 1 x 10-19 square centimeters were obtained for these cross sections.
