中文摘要
    Nd:YAG产生的二倍频532nm激光消融钛金属靶表面,产生钛金属蒸汽,同时含有3%乙炔的氦载气喷向旋转的金属靶,通过等离子体反应形成中性的气相金属?碳链团簇分子, 经过266nm的激光电离,在飞行时间质谱仪上获得了 (x = 0-4)和 团簇的离子信号。实验发现:对于 离子,含偶数碳原子的团簇离子信号较强。为了更好的理解金属碳笼的形成机理,利用Gaussian 09程序对 团簇离子进行了结构优化,获得了其稳定构型。它的形成可以看作是分别由两个Ti?C键连接的两个环状的 构成,也可以看作是由两个准线性的Ti?C?C键构成。
英文摘要
    The second-harmonic output of a Nd:YAG laser was used to ablate the surface of rotating metal rod. Thereafter, the metal was vaporized, and through plasma reactions with 3% acetylene which were carried in helium buffer gas, metal-carbon clusters were produced. After cluster species were ionized by the 266nm laser, (x = 0-4)and ion peaks were obtained in the time-of-flight (TOF) mass spectrometer. The experiment found that the cluster ions with even carbon atoms have strong signal for ions. In order to better understand the formation mechanism of the metal carbon cage, the structure of the cluster ions was optimized by Gaussian 09 program, and its stable configuration was obtained. The stable structures correspond to a connection through two Ti?C sides generating two new Ti?C bonds. Nevertheless, the final result of the interaction can also be viewed as two side-bonded quasi-linear Ti?C?C units.
