The authors studied the effect of an rf solenoid magnet and a partial Siberian snake on a stored 120 MeV vertically polarized proton beam. The {open_quotes}rf-induced{close_quotes} depolarizing resonance frequencies were measured for several partial Siberian snakes. The snake`s longitudinal field tilts the stable spin direction from the vertical and shifts the depolarizing resonances toward higher frequencies. A 4% snake shifts the resonance frequency by 11 kHz which corresponds to a spin tune shift of 0.00688. A partial Siberian snake should be able to overcome the relatively weak imperfection depolarizing resonances in proton accelerators up to about 10 GeV.
