Recent simulations of classical novae on oxygen-neon white-dwarf stars indicate that the isotopic ratio {sup 32}S/{sup 33}S has the potential to be a remarkable indicator of presolar grains of nova origin. The {sup 33}S(p,{gamma}){sup 34}Cl reaction influences this ratio directly by destroying {sup 33}S in novae. Additionally, {beta}-delayed {gamma} rays from the metastable state of {sup 34}Cl (t{sub 1/2}=32 min) have been suggested to be potential nova observables. We have measured the branches for known {sup 33}S(p,{gamma}){sup 34}Cl resonances that are activated at temperatures relevant to oxygen-neon novae. We provide the first reliable uncertainties on these branches and the first upper limits for several previously unmeasured branches.
