作者在自制的仪器上, 以脉冲激光(波长532nm, 能量密度10^8W/cm^2)在10^-^4Pa的真空中溅射合适的样品, 产生了一系列CnH^-、CnF^-和CnF3^-, 记录了它们的飞行时间质谱。

A series of cluster anions CnH-, CnF- and CnF3- with linear chain configuration were generated on a home-made apparatus by laser ablation. The stabilities of these anions depend strongly on the parity of the no. of the carbon atoms and can be understand by anal. of their bonding structures.

Key words: STRUCTURAL ANALYSIS, CARBON, LASER EVAPORATION, TIME-OFF FLIGHT MASS SPECTROMETRY
