Book Description
A new apparatus was constructed to deposit mass-selected molecular ions in cryogenic matrices. The successful mass-selection was demonstrated for CS2+ and C6F6+ cations in solid neon. These ions were examined using visible and IR absorption as well as laser excitation and laser induced fluorescence resulting in new insights into their spectroscopy. Additionally, the tungsten oxides WO and WO2 and the novel rare gas compounds HXeCl and HXeBr were characterized using conventional matrix isolation spectroscopy.

Book Description
Matrix-isolation spectroscopy, as a technique for studying unstable species, has had tremendous lasting powers. Since 1954, matrix-isolation has been able to assimilate new technology rather than being replaced by it. The matrix-isolation technique for producing and trapping new chemical species has been applied to an ever increasing range of chemical and physical problems since its inception. The last 12 years have seen a substantial number of new developments and applications of the matrix technique. The chapters in this book describe many of the contributions of matrix-isolation spectroscopy to chemistry and physics in the last decade, and as such predict the continued evolution of this technique over the next decade. Experimental techniques are generally closely related to the development of new apparatus, and each chapter has a section describing innovations in instrumentation such as the closed-cycle cryogenic cooler that has revolutionized the technique. In addition, each chapter describes many of the specialized methods used to prepare, trap and study particular new subject species. The volume will be an indispensable reference source for graduate students and other scientists new to this field, as well as chemists and physicists already involved in applied spectroscopy.

Book Description
The matrix isolation (MI) method has now been used for nearly thirty years. During this period it has been actively developed and the range of problems tackled greatly extended. Originally it was used for studies of transient species involv ing vibrational, electronic and ESR spectroscopy. Nowadays the study of transient species forms a comparatively small part of HI work since it has been amply demonstrated that very fruitful information can be obtained of the structure and interactions of stable molecules and their aggregates. In addition to the s~ectroscopic methods mentioned above the MI technique is nowadays a standard method in research based on vibrational relaxation, luminescence, Mossbauer, magnetic circular dichroism, pulsed NMR and photoelectron spectroscopy. The matrix isolation technique affords considerable advantages over more conventional methods in most applications of spectroscopy. Areas where the technique has been widely applied, or shows great potential, include: metal atom chemistry, and its relation to surface chemistry, high temperature inorganic species, transition metal complexes, interstellar species, free radicals and unstable molecules, conformational studies, molecular com plexes, and intermolecular forces.

Book Description
The fundamental role that Astrochemistry plays into regulating the processes that in interstellar clouds lead to the formation of stars, and how these processes concur into affecting the shape and the dynamics of galaxies and hence into showing the Universe in the way it appears to us is well established. Together with those occurring in the gas phase a special relevance is recognized to processes that involve interstellar dust grains, the solid component of matter diffused among stars. The school on "Solid State Astrochemistry", held at the Ettore Majorana Centre for Scientific Culture in Erice (Sicily) from the 5th to the 15th of June 2000, was the fifth course of the International School of Space Chemistry. In spite of its very focused aim it was attended by 66 participants from 17 different countries, that in the very special environment provided by the Majorana Centre, discussed in great details the various aspects of the subject.

Book Description
The mystery of the diffuse interstellar bands has been variously a curiosity, a co nundrum, and a nuisance for astronomers in the seven decades since the features were first noticed, but recently they have become a forefront issue in astrophysics. Ever since Paul Merrill, in a series of papers starting in 1934, pointed out the interstellar and unidentified nature of the bands, a Who's Who of twentieth century astronomers have tried their hands at solving the problem of identifying the carriers. Henry Norris Russell, Pol Swings, Otto Struve, Paul Ledoux, W. W. Morgan, Walter Adams, Jesse Greenstein, Lawrence Aller, and Gerhard Herzberg all briefly entered the stage, only to move on quickly to other problems where the chances for progress appeared more realistic. In more recent times a number of equally prominent scientists have pursued the bands, but generally only as a sideline to their real astronomical research. But in the past decade, and particularly in the past three years, the view of the search for the diffuse band absorbers as an interesting but perhaps quixotic quest has changed. Today there are several astronomers, as well as laboratory chemists, who are devoting substantial research time and resources to the problem and, as perhaps the most reliable indicator of the newly elevated status of research in this field, some research grants have now been awarded for the study of the bands.
