Multiconfigurational Quantum Chemistry
The first book to aid in the understanding of multiconfigurational quantum chemistry, Multiconfigurational Quantum Chemistry demystifies a subject that has historically been considered difficult to learn. Accessible to any reader with a background in quantum mechanics and quantum chemistry, the book contains illustrative examples showing how these methods can be used in various areas of chemistry, such as chemical reactions in ground and excited states, transition metal and other heavy element systems. The authors detail the drawbacks and limitations of DFT and coupled-cluster based methods and offer alternative, wavefunction-based methods more suitable for smaller molecules.

Die Chemilumineszenz der 2-Coumaranone
Die vorliegende Arbeit zeigt die Synthese, den Lumineszenzmechanismus als auch Applikation der 2-Coumaranone. Diese wurden mittels der Tscherniac-Einhorn-3-Komponenten-Reaktion hergestellt. Eine Großzahl der neu hergestellten Verbindungen ist in der Lage intensive baseninduzierte Chemilumineszenz zu zeigen. Dabei zählen die 2-Coumaranone zu den effizientesten aktuell bekannten Chemilumineszenzsystemen und emittieren Licht meinst im blauen Spektalbereich. Der in der Literatur postulierte Chemilumineszenzmechanismus wurde sowohl experimentell, als auch quantenchemisch untersucht und in seinen fundamentallen Schritten vollständig aufgeklärt. Hierbei spielt beim Angriff des Sauerstoffs am deprotonierten 2-Coumaranon ein Einzelelektronentransfer eine Schlüsselrolle. Der Zerfall des reaktiven Intermediates, eines 1,2-Dioxetanons, innerhalb des Mechanismus konnte sowohl im Grundzustand, als auch im angeregten Zustand beschrieben werden. Der Emitter der Chemilumineszenzreaktion wurde identifiziert und synthetisiert. Seine strukturelle Kenntnis erlaubt die Vorhersage der Emissionseigenschaften einer großen Vielzahl neuer 2-Coumaranone.

Lanthanide-Based Multifunctional Materials
Lanthanide-Based Multifunctional Materials: From OLEDs to SIMs serves as a comprehensive and state-of the art review on these promising compounds, delivering a panorama of their extensive and rapidly growing applications. After an introductory chapter on the theoretical description of the optical and magnetic behaviour of lanthanides and on the prediction of their properties by ab-initio methods, four chapters are devoted to lanthanide-based OLEDs, including the latest trends in visible emitters, the emerging field of near infrared emitters and the first achievements attained in the field of chiral OLEDs. The use of lanthanide complexes as molecular magnets spreads over another two chapters,...
Handbook of Software Solutions for ICME
As one of the results of an ambitious project, this handbook provides a well-structured directory of globally available software tools in the area of Integrated Computational Materials Engineering (ICME). The compilation covers models, software tools, and numerical methods allowing describing electronic, atomistic, and mesoscopic phenomena, which in their combination determine the microstructure and the properties of materials. It reaches out to simulations of component manufacture comprising primary shaping, forming, joining, coating, heat treatment, and machining processes. Models and tools addressing the in-service behavior like fatigue, corrosion, and eventually recycling complete the co...
