We report resonance enhanced multiphoton ionization (REMPI) spectra of gas-phase indium monochloride (InCl) between 330 and 490 nm. The spectra originate from one-, two-, and three-photon resonances with electronic states that reside between 27 000 and 75 000 cm(-1). We assign 12 new Rydberg states. From these Rydberg origins we can extrapolate the adiabatic ionization potential IPa=77 460+/-600 cm(-1) (9.60+/-00.08 eV). The Rydberg states exhibit vibrational frequencies ranging between 307 and 355 cm(-1).
