SiCl radical is observed from 430 to 520 nm by resonance enhanced multiphoton ionization. The spectra arise from two photon transitions to the C 2Pir, D 2Sigma+, and E states. Absorption of a third laser photon formed the cation. Both higher vibrations of the C 2Pir state (v[script ']=3–7) and the Si37Cl spectrum of the C 2Pir state are observed. The Si35Cl C 2Pir state vibrations can be fit with constants of omegae=682.7±3.8 cm−1 and omegaexe=3.8±0.5 cm−1.
