The Advanced Research Workshop entitled “Weakly Interacting Molecular Pairs: Unconventional Absorbers of Radiation in the At- sphere” was held in Abbaye de Fontevraud, France, from April 29 to May 3, 2002. The meeting involved 40 researchers from 14 countries. The goal of this meeting was to address a problem that the scienti?c community is aware of for many years. Up now, however, the so- tion for this problem is far from satisfactory. Pair e?ects are called unconventional in the title of this meeting. In speci?c spectral domains and/or geophysical conditions they are recognized to play a dominant role in the absorption/emission properties of the atmosphere. Water vapor continuum absorption is among the most prominent examples. Permanently improving accuracy of both laboratory studies and ?eld observations requires better knowledge of the spectroscopic features - tributable to molecular pairs which may form at equilibrium. The Workshop was targeted both to clarify the pending questions and, as far as feasible, to trace the path to possible answers since the underlying phenomena are yet incompletely understood and since a reliable theory is often not available. On the other hand, the lack of precise laboratory data on bimolecular absorption is often precluding the construction of reliable theoretical models. Ideally, the knowledge accumulated in the course of laboratory studies should correlate with the practical demands from those who are carrying out atmospheric ?eld measurements and space observations.

Gas phase molecular spectroscopy is a powerful tool for obtaining information on the geometry and internal structure of isolated molecules and their interactions with others. It enables the understanding and description, through measurements and modeling, of the influence of pressure on light absorption, emission, and scattering by gas molecules, which must be taken into account for the correct analysis and prediction of the resulting spectra. Collisional Effects on Molecular Spectra: Laboratory Experiments and Models, Consequences for Applications, Second Edition provides an updated review of current experimental techniques, theoretical knowledge, and practical applications. After an introduction to collisional effects on molecular spectra, the book moves on by taking a threefold approach: it highlights key models, reviews available data, and discusses the consequences for applications. These include areas such as heat transfer, remote sensing, optical sounding, metrology, probing of gas media, and climate predictions. This second edition also contains, with respect to the first one, significant amounts of new information, including 23 figures, 8 tables, and around 700 references.Drawing on the extensive experience of its expert authors, Collisional Effects on Molecular Spectra: Laboratory Experiments and Models, Consequences for Applications, Second Edition, is a valuable guide for all those involved with sourcing, researching, interpreting, or applying gas phase molecular spectroscopy techniques across a range of fields. Provides updated information on the latest advances in the field, including isolated line shapes, line-broadening and -shifting, line-mixing, the far wings and associated continua, and collision-induced absorption Reviews recently developed experimental techniques of high accuracy and sensitivity Highlights the latest practical applications in areas such as metrology, probing of gas media, and climate prediction

This book is devoted to the most efficient method of obtaining spectroscopic parameters characterising the absorption of microwave radiation by the Earth’s atmosphere. It explores why this field of science is interesting and important for humanity, and details the basics of gas phase molecular spectroscopy. The book also shows the advantages of the resonator spectroscopy technique for quantitative molecular analysis, and reviews the best-known investigations of diagnostic atmospheric lines and the continuum in the millimetre and submillimetre-wave range. It will appeal to a wide range of specialists in the fields of spectroscopy, atmospheric physics, and millimetre and submillimetre-wave techniques, and will be helpful for lecturers and students concerned with these specialised courses.

Types and Properties of Water in two volumes is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. These volumes deal with different parts of the hydrosphere and features of water as substance in its three phases. Natural water is one of the most important substances for the maintenance of life on our planet. The main part of the Earth's water is concentrated in the hydrosphere (oceans, lakes, streams, underground water), and in the cryosphere (all the snow and ice). The atmosphere and living organisms also contain water, but in minor quantities as compared to the whole hydrosphere. Several types of water are in the Nature: atmospheric water, water in oceans, seas, coastal zones, and estuaries; in rivers, reservoirs, lakes and wetlands; groundwater including soil waters; glaciers, icebergs, and ground ice (permafrost). This set of volumes is designed to be a very authoritative reference for state-of-the-art knowledge on the various aspects such as: Characteristics of Water and Water Bodies in the Natural Environment; Properties of Atmospheric Water; Properties of Oceans, Inland Seas, Coastal Zones, and Estuaries; Properties of Rivers, Streams, Lakes and Wetlands; Properties of Soil Water and Groundwater; Properties Of Glacial, Iceberg And Permafrost Water. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
