Un système de spectroscopie Auger basé sur un analyseur hémisphérique et balayage des énergies électroniques de 0 à 3000 eV a été construit et testé. Outre l'appareil de mesure proprement-dit, le développement a porté sur la construction d'une enceinte de travail, avec porte-échatillon et passages électriques pouvant supporter un vide extrêmement poussé (de l'ordre du nano-Pascal). L'appareil a été appliqué à l'étude d'échantillons de verre, afin de mieux comprendre les phénomènes de vieillissement du verre en atmosphère humide et l'adhérence de l'étain pour la fabrication de miroirs. L'originalité de la thèse est d'avoir pu identifier un certain nombre de conditions opératoires optimales, de manière à pouvoir travailler avec le verre, matériau isolant électrique. En effet, la spectroscopie des électrons Auger est basée sur le bombardement de l'échantillon par un faisceau d'électrons, qui s'accumulent dans le matériau isolant et font fortement dériver les pics de rétro-diffusion.

The thesis is subdivided in four parts and two annexes . The first part concerns the choice of Strychnos usambarensis based on ethnobotanical considerations; the second part is dedicated to the study of arrow poisons in the World and particularly in Africa; the third part describes the isolation of eight indole alkaoids ( 5 new and 3 known ones) and their structure determination thanks to modern spectroscopic methods.The fourth part is applied to the biosynthesis of these alkaloids and to the identification of loganic acid.The first appendix describes the phytochemical screening of 33 Rwandan plants mainly collected in the National Park of Akagera. The second appendix relates pharmacological experiments on crude fractions and some isolated alkaloids. [less ▲]

The relationships between the ionization energy (IE) of a donor compound and the position of the UV photoabsorption band of the complex of this donor with iodine as an acceptor are carefully analyzed. Their specificity with respect to (i) the adiabatic and vertical IE and (ii) the nature of the ionized orbital (n or pi) is examined. This analysis allowed us to attempt to determine the nature of the molecular orbital (MO) involved in the ionization process of ethylenimine, ethylene oxide and ethylene sulfide. Very likely the first IE corresponds to the ionization of the non-bonding (n) orbital located on the N and O atoms. Owing to the closeness of the "n" and "pi" IE for sulfides, in the case of ethylene sulfide no conclusion could be drawn. [less ▲]

The aim of this work is to investigate the appearance of negative ions by both the mechanism of Dissociative Electron Attachment (DEA) and Ion Pair processes (IPP) by electron impact. Using the appropriate instrumentation (a conventional Nier type mass spectrometer) the best conditions are chosen to ensure ion-molecule collision free ion production (sample pressure, impinging electron beam current), the linearity of the electron energy scale between 2 eV and 100 eV and to minimize mass (and translational kinetic energy) discrimination. The used ionizing electron beam allowed us a resolution of 0.5 eV. An ionization model for both processes is proposed to provide us a method for the measurement of the threshold energy of DEA and IPP. Were necessary the numerical derivation of the ion current (for IPP) and the deconvolution of the ionization efficiency curves (for both DEA and IPP) are applied to increase the accuracy of the threshold energy determination and the resolution of the successive ion producing processes to be observed. DEA and IPP’s are observed and threshold energies are measured and assigned in: (i) diatomic molecules, i.e. H2, CO, NO and O2, (ii) triatomic molecules, i.e. CO2 and CS2 along the reaction paths providing O- and S- and CS-. No CO- ion has been detected. (iii) polyatomic molecules, i.e. CH4, C2H2, C2H4, C2H3F and C2H3Cl. Beside the monoatomic negative ions (H-, C-), diatomic and polyatomic negative ions are detected. For several of these species the electron affinity (EA) of the radical is not known, e.g. CH, C2 and C2H. From the appearance of the corresponding negative ions and threshold measurements this fundamental quantity has been deduced. In the particular case of C2-, the production of the negative ion in an electronically excited state has been put forward for the first time. Dissociation energies of the same diatomic and triatomic negative ions have been deduced and compared with this same magnitude in neutral and positive ionic species. [less ▲]
