Zusammenfassung: <jats:p>The dependence of the field ionization behaviour of olefines on field-induced surface reactions is demonstrated using 1-Hexene as an example. Different emitter- and field strength dependent reaction mechanisms leading to the production of (M+1)<jats:sup>+</jats:sup> and (M-1)<jats:sup>+</jats:sup> ions may be distinguished. The characteristics of define spectra taken using activated emitters are determined largely by surface induced reactions which appear at higher field strengths. These have as their starting point an ionic field adsorption of the olefine. In particular the field enhancement of the organic microneedles is strongly influenced by field adsorbed ions so that field dissociation products are also measured with increased intensity.</jats:p>
