Clarifying chemical processes in the environment is tantamount to creating a better and a safer planet. The chemistry that takes place within the natural world occurs not only in the bulk gaseous, liquid, and solid phases, but also in the region where two phases meet. This molecularly thin region between phases, also known as an interface, plays a significant role in various chemical processes because interfaces are ubiquitous in nature. Despite the significance of interfacial processes in environmental chemistry, investigating environmental interfaces experimentally has always been a challenge. Recent advances in nonlinear spectroscopy (NLS) have demonstrated that techniques such as sum frequency generation (SFG) and second harmonic generation (SHG) are unique in their ability to probe buried chemical interfaces. The theoretical and practical aspect of these techniques in probing environmental interfaces is the primary focus of this e-book. This e-book is geared toward curious and inquisitive minds eager to learn how molecules behave at the thin layers of chemical interfaces. A beautiful world, rich in unique insights into the interfacial environmental processes, awaits.
The advent of laser-based sources of ultrafast infrared pulses has extended the study of very fast molecular dynamics to the observation of processes manifested through their effects on the vibrations of molecules. In addition, non-linear infrared spectroscopic techniques make it possible to examine intra- and intermolecular interactions and how su
The exceptional quality of previous editions has been built upon to make the twelfth edition of Atkins' Physical Chemistry even more closely suited to the needs of both lecturers and students. The writing style has been refreshed in collaboration with current students of physical chemistry in order to retain the clarity for which the book is recognised while mirroring the way you read and engage with information.The new edition is now available as an enhanced e-book, which offers you a richer, more dynamic learning experience. It does this by incorporating digital enhancements that are carefully curated and thoughtfully inserted at meaningful points to enhance the learning experience. In add...
Panorama musical vocal profano de Castilla y León de 1985 a 1994 a través de fuentes primarias inéditas y otras ya grabadas, realizado con la información que nos dejaron los programas Raíces y El Candil de Radio Nacional de España.También se muestran los intérpretes más representativos, los géneros y especies musicales vinculados al repertorio vocal profano expuesto, el contexto social y cultural donde se ejecutaban dichas tonadas, la visión organológica de los instrumentos populares con los que se acompañan, las sonoridades, estructuras, mensuras poéticas y ritmos más característicos, etc., todo ello gracias al trabajo de campo hecho por Gonzalo Pérez Trascasa y Ramón Marijuán Adrián, acompañados por Luis González Jiménez y Néstor Cuñado Valdivielso como técnicos de sonido. En la propia investigación se adjuntan seiscientos cuarenta y ocho documentos musicales que se añaden, tras su estudio y transcripción, al patrimonio cultural inmaterial de Castilla y León.
