Abstract
We investigate the influence of the R-parity violating couplings lambda, lambda' and lambda'' on the branching ratio of b to s gamma in leading logarithmic approximation. The operator basis is enlarged and the corresponding gamma-matrix calculated. The matching conditions receive new contributions from the R-parity violating sector. The comparison with the experiment is rather difficult due to the model dependence of the result.
