Helping you better understand the processes, instruments, and methods of aerosol spectroscopy, Fundamentals and Applications in Aerosol Spectroscopy provides an overview of the state of the art in this rapidly developing field. It covers fundamental aspects of aerosol spectroscopy, applications to atmospherically and astronomically relevant problem
Radioastronomy has painted an extraordinary picture of the Galactic interstellar medium, which displays an amazing organization and structuring of matter from very hot ultra-diluted media to very cold denser milieus considered as the cradles of stars. In these latter environments, the discovery of a chemical diversity of molecules, including those associated with precursors to life itself, immediately brought to light the question of the mechanisms leading to their formation and persistence at temperatures as low as 10 K. The chemical networks developed to understand telescope observations required a great deal of physical and chemical parameters relevant to interstellar conditions, particul...
In the present work the carboxylic acid dimers and water clusters are chosen as model systems of strong and moderately strong hydrogen bonds and studied with spontaneous Raman spectroscopy coupled with a supersonic jet expansion. The spectra of several carboxylic acids are measured and assigned in the entire fundamental wavenumber region. An overview of their vibrations is achieved by comparing our experimental results with former experimental results as well as with quantum chemical calculations. For the first time, we know from experiment how anharmonic the hydrogen bond vibrations of formic acid are and it is proved that the hydrogen bond becomes stiffer when moving from formic acid to acetic acid. Now there is a very complete spectroscopic data base for formic acid dimer, which can be used to rigorously test quantum chemical calculations. Besides, we finally know from experiment how strongly the OH oscillators are coupled to each other in the simplest ring clusters of water. All this was only possible by the use of spontaneous Raman scattering in supersonic expansions, which is a really powerful tool to investigate hydrogen bonded systems.
In 2016 the Swiss Society for Meteorology (Schweizerische Gesellschaft für Meteorologie, SGM) celebrates its 100th anniversary. Compared to other meteorological societies it is not among the oldest ones. Nevertheless, meteorology has gone through such a remarkable evolution in the past 100 years that it is worthwhile to take a look back and recapitulate the developments of both science and SGM – and to reveal their interaction. The idea of this book is to give an overview of what has happened in the field of atmospheric sciences in Switzerland since the first systematic long-term meteorological observations until today.

Spectroscopic Properties of Inorganic and Organometallic Compounds: Techniques, Materials and Applications provides a unique source of information in an important area of chemistry. Since Volume 40 the nature and ethos of this series have been altered to reflect a change of emphasis towards 'Techniques, Materials and Applications'. Researchers will now find up-to-date critical reviews which provide in-depth analyses of the leading papers in the field, with authors commenting of the quality and value of the work in a wider context. Focus areas will include structure-function relationships, photochemistry and spectroscopy of inorganic complexes, and catalysis; materials such as ceramics, cements, pigments, glasses and corrosion products; techniques such as advanced laser spectroscopy and theoretical methods.
