Abstract Optical spectra of molecular species sputtered from nitrogen, and carbon-oxygen implanted silicon are analysed and compared with the predictions of the accompanying theoretical paper. The dominant emission in both systems corresponds to the extensive rovibrational excitation predicted for a sputtering source. The molecules N2, CO, and/or CO+ appear to be the primary electronically excited species. The N2 excitation mechanism in the nitrogen-silicon system is suggested to be similar to that producing the Lewis-Rayleigh afterglow, namely, the associative reaction N(4S0) + N(4S0)⇌N 2 5 ∑ g + followed by the stabilization mechanism N 2 5 ∑ g + +M⇌N2B3 Π g +M, whereM represents the surface. Additional weak SiNB2 ∑ +, N2C3 Π u and N 2 5 B2 ∑ u + excitation is analysed, and its origin discussed.
