Título: | Complex internal rearrangement processes triggered by electron transfer to acetic acid |
Autor: | Limão-Vieira, P.; Meneses, G.; Cunha, T.; Gil, A.; Calhorda, Maria José; García, Gustavo CSIC ORCID; Ferreira da Silva, F. | Fecha de publicación: | 2015 | Editor: | Institute of Physics Publishing | Citación: | Journal of Physics: Conference Series 635: 012002 (2015) | Resumen: | We present negative ion formation from collisions of 100 eV neutral potassium atoms with acetic acid (CH3COOH) and its deuterated analogue molecules (CH3COOD, CD3COOH). From the negative ion time-of-flight (TOF) mass spectra, OH- is the main fragment detected accounting on average for more than 25% of the total anion yield. The complex internal rearrangement processes triggered by electron transfer to acetic acid have been evaluated with the help of theoretical calculations at the DFT levels explaining the fragmentation channel yielding OH-. | Descripción: | 8 págs.; 4 figs.; XXIX International Conference on Photonic, Electronic, and Atomic Collisions (ICPEAC2015); Open Access funded by Creative Commons Atribution Licence 3.0 | Versión del editor: | http://dx.doi.org/10.1088/1742-6596/635/1/012002 | URI: | http://hdl.handle.net/10261/135208 | DOI: | 10.1088/1742-6596/635/1/012002 | Identificadores: | doi: 10.1088/1742-6596/635/1/012002 issn: 1742-6588 |
