| Abstract: | We have developed a setup that could produce gas phase metal compound molecules and ions by discharging assisted laser ablation. The ionic and neutral radical products have been investigated by the time-of-flight mass spectroscopy (TOF-MS) and laser-induced fluorescence spectroscopy (LIFs), respectively. The results showed that this setup could produce gas phase metal compound radical molecule ions with a high yield and low temperature. Therefore, this source may help researchers in laser spectroscopic research on metal compound molecules. |
