Abstract

Photodissociation thresholds of OH from CH₃OH in solid Ne and Ar were determined via photolysis of CH₃OH/Ne and CH₃OH/Ar (1/200) samples in situ at 4 K. The samples were irradiated with VUV synchrotron radiation after dispersion by a Seya-Nainioka monochromator. The OH photo-product was detected by means of laser-induced fluorescence technique. The increase of fluorescent intensity of OH was monitored and recorded after the matrix sample was irradiated at different wavelengths for 3-5 min. Photodissociation threshold energies of 7.13 ± 0.02 eV (174.0 ± 0.5nm) and 7.08 ± 0.04eV (175.0 ± 1.0nm) were measured for OH production of CH₃OH in solid Ne and Ar, respectively.
