title: Ionization spectroscopy of a DNA base: vacuum-ultraviolet mass-analyzed threshold ionization spectroscopy of jet-cooled thymine.
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.
