La química es la ciencia que describe todo lo que existe. A lo largo de veinte capítulos cautivadores, con un tono ameno y divertido, Héctor Busto desglosa las particularidades de la química y todas las formas en que interviene en nuestras vidas sin que reparemos mucho en ello, desde su aplicacion en medicina hasta la fabricacion de cualquier producto, ya sea en la industria alimentaria o la construccion de un rascacielos, la invencion de un color o la reproduccion de un aroma. Y aunque parece que tenga algo de magia, la quimica consiste en comprender (y transformar) la materia que nos rodea.

El libro consta de 200 problemas de determinación estructural de compuestos orgánicos mediante técnicas espectroscópicas. Cada problema incluye el espectro infrarrojo y los espectros de resonancia magnetica nuclear de 1H y 13C de un compuesto organico problema de tal manera que la utilizacion conjunta de ambas tecnicas, junto con el dato de la formula molecular, permita al estudiante una determinacion logica y razonada de la estructura del compuesto organico. Con la finalidad de mostrar al estudiante el camino a seguir, se dan las soluciones razonadas de los cincuenta primeros problemas. Las soluciones de los 150 problemas restantes se pueden obtener solicitandolas a los autores.Los espectros presentados fueron obtenidos a partir de muestras reales en las condiciones indicadas en cada caso. Todos los espectros de RMN de 1H fueron obtenidos a 300 MHz y los de 13C a 75 MHz en un espectrometro Bruker Avance 300. Los espectros IR fueron registrados en un espectrometro Nicolet Avatar 320 FTIR.

A. H. Munsells book A Color Notation is a groundbreaking tome that revolutionized the study of color theory. Published in 1905, this seminal work introduced a systematic method of classifying colors based on hue, value, and chroma. Munsells precise and scientific approach to color notation paved the way for modern color theory and design. By illustrating the three-dimensional model of color space, Munsell provided artists and designers with a practical tool for understanding and utilizing color in their works. A. H. Munsell, a noted artist and educator, was inspired to create A Color Notation by his frustration with the lack of a standardized color system. His extensive research and experimentation led him to develop the Munsell Color Order System, which has since become the industry standard for color classification. Munsells expertise in color theory and his passion for improving the quality of artistic expression shine through in this influential book. I highly recommend A Color Notation to anyone interested in art, design, or color theory. Munsells systematic approach to understanding color is both educational and inspiring, making this book a must-read for anyone looking to deepen their knowledge of visual aesthetics.
