the kinetics of their photolyticcleavage examined in solution. The linkers were prepared by amidation of the carboxylic acid anchoring tether with benzylamine, and the cleavable benzylic substituent was chosen to be either acetic acid or acetamide. Irradiation of the linkers in four solvents (methanol, p-dioxane, and aqueous buffer +/- dithiothreitol) at 365 nm and analysis via HPLC afforded kinetic
