LP Vera, JA Pérez, H Riascos

Spectroscopic analysis of plasma produced by laser ablation of coal samples using 1064 nm radiation pulses from a Q-switched Nd: YAG on different target under air ambient, was performed. The emission of molecular band systems such as C2 Swan System (d3Πg→ a3Πu), the First Negative System N2 (Band head at 501, 53 nm) and emission lines of the CI, C II, were investigated using the optical emission spectroscopy technique. The C2 molecular spectra (Swan band) were analyzed to determine vibrational temperature (0, 62 ...
