Angle, energy and mass-resolved ion spectroscopy of core-excited polyatomic molecules

Linear and reflectron type time-of-flight (TOF) mass spectrometers were used to study chemical reactions of the core-excited large molecules. A linear TOF mass spectrometer was useful for studying an angle-resolved photofragmentation of the core-excited polyatomic molecule. A reflectron type TOF mass spectrometer was powerful to investigate the site-specific photofragmentation. These mass spectrometers were installed as a part of the endstation of the beamline BL8B1 at UVSOR facility of the Institute for Molecular Science, and some features of them are presented in this paper.
