The excitation energies of the proton unbound states in [sup 32]Cl have been measured in the [sup 32]S([sup 3]He,[ital t])[sup 32]Cl charge exchange reaction with high accuracy. The partial widths of the unbound levels have been calculated to derive the resonance strengths of these states in the [sup 31]S([ital p],[gamma])[sup 32]Cl reaction channel. The reaction rate for the [sup 31]S([ital p],[gamma])[sup 32]Cl reaction has been calculated and is compared with previous estimates. The role of this reaction for the closure of the SiP cycle is discussed in terms of the temperature and density conditions in hot stellar hydrogen burning.
