Spectroscopic study on the reactive transition-metal species developed by the chemical sputtering method at very low temperature

利用毫米波光谱对低温化学溅射法制备的反应过渡金属进行了物理化学性质的研究。我们主要研究了以下几种物质，(1)过渡金属单硫化物和单氢硫化物作为硫酸盐稳定金属纳米簇的第一模型，(2)过渡金属单乙酰酯作为最简单的有机金属化合物，(3)10-族金属单卤化物作为10-族金属催化剂上单键的最简单模型。对这些物质的物理化学性质，如分子结构、键性质和不成对电子分布进行了详细的研究。

Reactive transition-metal species, which were generated by the chemical sputtering method at very low temperature, were observed by millimeter-wave spectroscopy to reveal their physico-chemical properties. We mainly studied on the following species, (1) transition-metal monosulfides and monohydrosulfides as the first model for the thiorate-stabilized metal-nanocluster, (2) transition-metal monoacetilides as the simplest organometallics, (3) the group-10-metal monohalides as the simplest model for the single bond on the group-10-metalic catalyst. For these species, the physico-chemical properties, such as molecular structure, bond character, and unpaired electron distribution, were explored in detail.
