✦ Synopsis

The decomposition mechanism of SiHa('B, ) formed after IR multiple-photon dissociation of SiH., has been investigated by simultaneous acquisition of spontaneous chemiluminescence of SiHr radicals and state-selective two-photon laser-induced fluorescence spectra of the atomic silicon produced Evidence for the opening of an effkient dissociation channel leading to Si( 'D2) +H2( 'Z: ) from high vibrational levels of the SiHr( 'B,) state is presented and discussed.
