锗烷在其伸缩振动泛频态上会出现局域模振动,这不仅对研究分子在激发态上的行为有重要意义,而且它所揭示的形成局域模振动的机制普遍适用于任何分子,从而为选键化学带来新希望。在0.005cm~-1分辨率上记录了锗烷的6040～6420cm~(-1)区域的泛频光谱。它们是(3000)和(2100)伸缩振动泛频带。其中,(3000)谱带具有对称陀螺分子平行谱带的K结构,并分辨出4种同位素分子的谱线。采用简正模和局域模两种图象对这一光谱进行了解释和分析,并讨论了其局域模振动的行为。
Local mode vibration of germane occurs at its extended vibrational vibrational frequency, which is not only important for studying the behavior of molecules in the excited state, but also the mechanism of forming local mode vibration revealed by it is generally applicable to any molecule, Thus bringing new hope for the selective bonding chemistry. In the resolution of 0.005cm ~ -1, the ubiquitous spectra of 6040 ~ 6420cm ~ (-1) region of germane were recorded. They are (3000) and (2100) stretching vibration pan frequency bands. Among them, the (3000) band has the K structure of the parallel bands of symmetric gyroscopic molecules and the spectral lines of the four kinds of isotopic molecules are distinguished. This spectrum was interpreted and analyzed using both normal and local modes, and the local mode vibration was also discussed.
