Abstract
The high-resolution ionization spectroscopy of DNA bases is reported for the first time. Vacuum-UV mass-analyzed threshold ionization (VUV-MATI) spectrum of jet-cooled thymine provides not only the most precise ionization potential but also its vibrational structure in the ground cationic state.
摘要
首次报道了DNA碱基的高分辨率电离光谱。喷射冷却胸腺嘧啶的真空紫外光质量分析阈值电离（VUV-MATI）光谱不仅提供了最精确的电离能，还提供了其基态阳离子态的振动结构。
