Soft x-ray ionization and fragmentation of n- and iso-propanol
(1998) In Journal of Physics B: Atomic, Molecular and Optical Physics 31(15). p.3407-3418- Abstract
- Threshold electron and total ion yield spectra are presented for the near C and O 1s edge photoexcitation of n- and iso-propanol. To our knowledge these are the first such data for iso-propanol, and represent the first direct measurement of the core ionization energies of these molecules by threshold photoelectron spectroscopy. In particular, the C 1s energies for n-propanol are found to be lower (by about 0.5 eV) than determined indirectly in a previous study. Application of multiple coincidence techniques has enabled determination of the branching ratios of the dissociative multiple ionization channels uniquely associated with each core edge in both molecules. These show evidence for a greater degree of energy localization in n-propanol... (More)
