Acesso restrito. p. 145–149Photon stimulated ion desorption (PSID) and Near-edge X-ray absorption fine structure (NEXAFS) studies have been performed on poly(vinyl chloride) (PVC) and poly(vinyl dichloride) (PVDC) around the chlorine 1s-edge. Experiments were performed using a synchrotron source operating in the single-bunch mode and a time-of-flight mass spectrometry for ion analysis. Cl+ ion yields, as a function of the photon energy, reproduce the photoabsorption spectrum, showing significant increase at the 1s-resonance. Edge-jump ratios, defined as the ratio between edge-jumps (intensity ratio of the yields between above and below the absorption edge) of two different transitions, for Cl+ ion yields were much higher than the equivalent electron yields, indicating site-selectivity in C–Cl bond breaking for both polymers, as a result of efficient spectator Auger decay. The expected isotope ratio of 3:1 for chlorine was measured for PVC. The interpretation of the NEXAFS spectrum was assisted by quantum mechanical calculations at a multireference perturbation theory level.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-06-25T17:17:04Z No. of bitstreams: 1 7777777777777777.pdf: 404289 bytes, checksum: 4ce753d009c9fcad428f2e646e1f2de2 (MD5)Rejected by Alda Lima da Silva(sivalda@ufba.br), reason: Material de Física on 2013-08-16T19:00:40Z (GMT)Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-08-19T16:48:16Z No. of bitstreams: 1 7777777777777777.pdf: 404289 bytes, checksum: 4ce753d009c9fcad428f2e646e1f2de2 (MD5)Rejected by Alda Lima da Silva(sivalda@ufba.br), reason: Unidade fora da demanda on 2013-08-23T22:06:40Z (GMT)Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-08-26T12:03:46Z No. of bitstreams: 1 7777777777777777.pdf: 404289 bytes, checksum: 4ce753d009c9fcad428f2e646e1f2de2 (MD5)Approved for entry into archive by Vilma Conceição(vilmagc@ufba.br) on 2013-09-02T18:02:02Z (GMT) No. of bitstreams: 1 7777777777777777.pdf: 404289 bytes, checksum: 4ce753d009c9fcad428f2e646e1f2de2 (MD5)Made available in DSpace on 2013-09-02T18:02:02Z (GMT).
