氢分子在原子纳米腔中的皮米级光谱学研究Picometric Spectroscopy of Hydrogen Molecules in Atomic Nanocavities
➀ 科学家首次利用针尖增强拉曼光谱（TERS）在原子级皮米腔内观测到氢（H₂）与氘（D₂）分子的光谱特征；
➁ 核量子效应（如量子扩展）导致H₂与D₂的振动模式差异，揭示了传统光谱无法探测的同位素特异性现象；
➂ 该研究为氢存储材料设计、催化反应分析及单分子量子调控技术提供了新方向。
➀ Scientists achieved the first spectroscopic observation of hydrogen (H₂) and deuterium (D₂) molecules confined in atomic-scale picocavities using advanced tip-enhanced Raman spectroscopy (TERS);
➁ Quantum mechanical effects, such as nuclear delocalization, were identified as the cause of distinct vibrational responses between H₂ and D₂, revealing isotope-specific behavior not detectable by conventional methods;
➂ The findings offer new insights for energy storage systems, catalytic surfaces, and single-molecule quantum control technologies.
