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 ex-perimental 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.
