分子波函数的直接观测

Visualizing wavefunctions in molecules

  • 摘要: 2011年,IBM苏黎世实验室根据量子力学中隧道效应的“微商定则”,用一氧化碳分子作为扫描隧道显微镜的探头,观测到了两种有机分子的波函数的波节面和叶片在空间中的分布,证明了分子波函数的波节面和叶片结构是可以直接观测的物理实在。反映上述研究工作结果的文章发表一年多以来,已获得物理学界和化学界的普遍认同。这一实验发现将帮助未来几代的化学家对分子的性质有直观的了解,从而引导他们在化学的所有领域中获得新的解决方案。

     

    Abstract: In 2011, the Zurich Laboratory of IBM Research Division, based on the derivative rule of tunneling theory, using a CO-terminated tip, made high-resolution molecular orbital imaging with a direct observation of the nodal structure of individual wavefunctions in organic molecules. The experimental breakthrough will help future generations of chemists in obtaining an intuitive understanding of molecular properties that will guide them to novel solutions in all areas of chemistry.
