AbstractThe free SiNSi radical has been investigated in a molecular free jet by laser induced fluorescence excitation and dispersed fluorescence spectroscopy. The radicals have been generated by laser ablation of Si in the presence of NH3 diluted (5%) in He. Excitation spectra of the B∼₂∑+u - X∼₂∏g system have been recorded in the 32600 - 36400 cm-1 range. For most of the excitation bands, dispersed fluorescence spectra have been obtained. Very large Renner-Teller interaction has been observed in both electronic states. The excitation and dispersed fluorescence spectra have been vibrationally and rotationally analyzed. Rotational, vibrational, and Renner-Teller parameters will be presented.
