Book Synopsis Resonancia Magnética Nuclear by : Javier Mencias
Download or read book Resonancia Magnética Nuclear written by Javier Mencias and published by Javier Mencias. This book was released on 2019-02-16 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Entre las técnicas más usuales de estudio de la materia, las diversas espectroscopias juegan un papel especialmente importante. La espectroscopia de resonancia magnética nuclear (RMN, o en inglés NMR, de Nuclear Magnetic Resonance) es un fenómeno físico descrito originalmente en 1946 por Felix Bloch y Edward Mills Purcell, que ganaron el Premio Nóbel de Física por este descubrimiento en 1952. La RMN se basa en la interacción entre núcleos atómicos bajo la influencia de un campo magnético externo y un campo electromagnético de una frecuencia determinada (ondas de radio). La RMN sirve para estudiar el comportamiento de ciertos núcleos atómicos, aquellos que poseen momento magnético, en presencia de un campo magnético externo. El campo aplicado es responsable de la ruptura de la degeneración de los niveles de energía de espín nuclear, de modo que pueden introducirse transiciones entre ellos como consecuencia de la absorción de radiación electromagnética adecuada. Puesto que la disposición de los niveles de energía es una propiedad tanto de los núcleos de una molécula como de su entorno electrónico y de las interacciones entre ambos, la espectroscopia de RMN es una herramienta de gran utilidad en la clasificación de sustancias. No es de extrañar que desde los primeros experimentos con éxito, llevados a cabo en 1945, la RMN haya tenido un desarrollo espectacular, en especial desde que en 1966 se introduce la espectroscopia de RMN en la modalidad de transformación de Fourier, que haya permitido incrementar ganancias de sensibilidad en uno o dos órdenes de magnitud, eliminando parcialmente una de las desventajas de la técnica. El desarrollo de nuevos métodos (RMN bidimensional, photo-CIDNP, excitación a medida...) y la construcción por las casas comerciales de imanes cada vez más potentes (ya son comerciales los imanes de 11.7 teslas) hacen prever que el límite de posibilidades de la técnica se halla todavía lejos de haber sido alcanzado, esperándose en el futuro que junto a una consolidación de los nuevos desarrollos, la ampliación del rango de aplicabilidad de esta técnica física, de por sí tremendamente amplio.

This book was released on 2018 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: La presente tesis doctoral se centra en el estudio de técnicas de mejora de resolución de la espectroscopía por Resonancia Magnética Nuclear (RMN) para una más simple y precisa elucidación estructural de moléculas pequeñas. El trabajo se ha presentado como un compendio de siete publicaciones escritas para diversas prestigiosas revistas científicas. Las publicaciones desarrollan en profundidad la aplicación de las mejoras de resolución para i) una medida precisa y eficiente de las constantes de acoplamiento tanto homo- como heteronucleares e ii) la optimización de las medidas de parámetros anisotrópicos a través de medios débilmente alineados. Estos dos tópicos se desarrollan mediante: 1.La aplicación de modernas técnicas de RMN para la mejora de laresolución, tanto digital como de señal, en experimentos 2D sin comprometer el tiempo experimental. 2.El diseño de nuevas secuencias de pulsos para la medida de conectividades de largo alcance heteronuclear. 3.La implementación de secuencias de pulsos ya existentes y el diseño de nuevas para el estudio de muestra en medio aniostrópicos. 4.El estudio de nuevos métodos en RMN para la discriminación mediante parámetros anisotrópicos. 5.La aplicación de protocolos para la automatización y simplificación de las medidas de contantes de acomplamientos en medio isotrópicos y anisotrópicos.
