Pełny tekst źródłaEsta tesis doctoral describe el uso de datos de alta resolución de difracción de rayos X de monocristal para la obtención de mapas experimentales detallados de distribución de densidad de carga. Estos mapas sirven para evidenciar experimentalmente la existencia de interacciones intra- e inter-moleculares débiles dentro de la estructura del cristal. Los mapas de densidad de carga se obtienen mediante un refinamiento multipolar de la estructura cristalina. En concreto, este trabajo se centra en evidenciar experimentalmente las interacciones atractivas no covalente recientemente descritas teóricamente y que dan lugar a la formación de enlaces de tipo "sigma y pi hole". Los términos enlaces de Triel, tetrel, pnictogen y chalcogen fueron recientemente introducidos para referirse a estas interacciones en función del grupo (14, 15 y 16) al que pertenece el átomo implicado como centro electrofílico. El hecho de que estas interacciones sean muy débiles hace necesario la obtención de mapas de densidad electrónica muy precisos. También se han utilizado estos mapas de densidad electrónica para determinar experimental el momento cuadrupolar y el potencial electrostático molecular de una serie de anillos de fenilo con diferentes sustituyentes. Los datos experimentales obtenidos de esta forma han servido para validar los resultados de cálculos teóricos.
radiación de molibdeno para asignar la configuración absoluta de una serie de moléculas orgánicas. Las moléculas medidas fueron seleccionadas teniendo en cuenta que el elemento más pesado de su composición química fuera el oxígeno. Es bien conocido que la dispersión anómala de este tipo de compuestos es muy débil y dificulta la asignación de configuración absoluta mediante esta técnica. El resultados de este trabajo demuestran que la metodología empleada es muy efectivo para poder asignar inequívocamente la configuración absoluta correcta en este tipo de moléculas. This thesis uses high resolution single crystal X-ray diffraction data in order to obtain experimental detailed charge density distribution maps that can exhibit intra and intermolecular interactions. The charge density maps are obtained through the multipolar refinement. Particularly, this work focuses in lasts classified non-covalent attractive interactions due to sigma and pi holes, triel, tetrel, pnictogen and chalcogen bonds. The weakness of these interactions make necessary very accurate and precise maps. In the same manner, in this works they have been determined the quadrupolar moment and the molecular electrostatic potential of a series of phenyl rings substituted with different chemical groups. The experimental data obtained in this way have been used to validate theoretical predictions. Eventually in this work, high resolution single crystal X-ray diffraction data using molybdenum radiation has been employed to assign the absolute configuration of a series of organic molecules. The measured molecules were selected containing oxygen as heaviest atom since the anomalous dispersion of these kind of compounds is very weak. The use of high resolution data has been proved to be effective in order to unequivocally assign the correct absolute configuration in this kind of molecules.

This thesis presents a study on two types of X-ray diffraction methodologies applied to the characterization of amorphous materials. The purpose of this study was to assess the feasibility of measuring the diffractive spectrum of amorphous materials by Energy-Dispersive X-ray Diffraction (EDXRD) utilizing Cadmium Zinc Telluride detectors. The total scattering intensity (coherent plus incoherent scatter) spectra precisely measured by high-energy Wide-Angle X-ray Scattering (WAXS) were compared to the EDXRD spectra to determine the level of agreement between the two techniques. The EDXRD spectra were constructed by applying a spectra fusing technique which combined the EDXRD spectra collected at different scattering angles rendering a continuous total scattering spectrum. The spectra fusing technique extended the momentum transfer range of the observed scattered spectrum beyond the limitations of the X-ray source and CZT detection efficiencies. Agreement between the WAXS and fused EDXRD spectra was achieved. In addition, this thesis presents the atomic pair correlation functions and coordination numbers of the first coordination shell for four hydrogen peroxide solutions of varying mass concentrations using Empirical Potential Structural Refinement (EPSR). The results are compared to the state-of-the art ad initio quantum mechanical charge field molecular dynamics (QMCF MD) model of the hydrogen peroxide in solution to support the model's predictions on why hydrogen peroxide is stable in water. The EPSR results using the coherent scattering intensity calculated from the WAXS data set predicts a hydration shell of 6.4 molecules of water surrounding hydrogen peroxide. The results also indicate that hydrogen peroxide is more likely to behave as a proton donor than acceptor. These findings are in agreement with QMCF MD model of aqueous hydrogen peroxide.
