We analyze polarized Compton scattering which provides information on thespin-structure of the nucleon. For scattering processes with photon energies upto 100 MeV the spin-structure dependence can be encoded into four independentparameters-the so-called spin-polarizabilities $\gamma_i, i=1...4$ of thenucleon, which we calculate within the framework of the "small scale expansion"in SU(2) baryon chiral perturbation theory. Specific application is made to"forward" and "backward" spin- polarizabilities.Comment: 8 pages revtex file, separation between pion-pole and regular  contributions detailed + minor wording changes, results and conclusions  unchange
