Atoms and Molecules in Strong External Fields:Auflage 1998
This book systematically discusses the effects of static electric and magnetic and laser fields on the rotational, fine, and hyperfine structure of molecules and on interactions of molecules at sub-Kelvin temperatures. The theories of molecular interactions in the presence of external fields have been developed only recently, in order to address the experimental work with ultracold molecules. This text gives the first comprehensive discussion on intermolecular interactions in external fields. Topics of discussion in this book include: rotational, fine and hyperfine structure of molecular radicals; 1Sigma diatomic molecules; 2Sigma and 3 Sigma molecules; 2Pi molecules; external field traps for ultracold molecules; interactions of ultracold molecules; Feshbach resonances in molecular scattering; molecular collisions in dc fields; molecular collisions in reduced geometries. A tutorial for calculating the response of molecules to electric and magnetic fields with examples from research in ultracold physics, controlled chemistry, and molecular collisions in fields Molecules in Electromagnetic Fields is intended to serve as a tutorial for students beginning research, theoretical or experimental, in an area related to molecular physics. The author--a noted expert in the field--offers a systematic discussion of the effects of static and dynamic electric and magnetic fields on the rotational, fine, and hyperfine structure of molecules. The book illustrates how the concepts developed in ultracold physics research have led to what may be the beginning of controlled chemistry in the fully quantum regime. Offering a glimpse of the current state of the art research, this book suggests future research avenues for ultracold chemistry. The text describes theories needed to understand recent exciting developments in the research on trapping molecules, guiding molecular beams, laser control of molecular rotations, and external field control of microscopic intermolecular interactions. In addition, the author presents the description of scattering theory for molecules in electromagnetic fields and offers practical advice for students working on various aspects of molecular interactions. This important text: * Offers information on theeffects of electromagnetic fields on the structure of molecular energy levels * Includes thorough descriptions of the most useful theories for ultracold molecule researchers * Presents a wealth of illustrative examples from recent experimental and theoretical work * Contains helpful exercises that help to reinforce concepts presented throughout text Written for senior undergraduate and graduate students, professors, researchers, physicists, physical chemists, and chemical physicists, Molecules in Electromagnetic Fields is an interdisciplinary text describing theories and examples from the core of contemporary molecular physics.

Internal Torsiona, Abd El-Fattah Mostafa, Internal resistance is defined as the resistance between the molecules of the subject concerned with the study by the means of an external factor that is producing it. In the present work, the internal torsion res
Synthesis is at the core of organic chemistry. In order for compounds to be studied-be it as drugs, materials, or because of their physical properties- they have to be prepared, often in multistep synthetic sequences. Thus, the target compound is at the outset of synthesis planning. Synthesis involves creating the target compound from smaller, readily available building blocks. Immediately, questions arise: From which bui- ing blocks? In which sequence? By which reactions? Nature creates many highly complex ´´natural products´´ via reaction cascades, in which an asso- ment of starting compounds present within the cell is transformed by speci c (for each target structure) combinations of modular enzymes in speci c - quences into the target compounds [1, 2]. To mimic this ef ciency is the dream of an ideal synthesis . However, we are at present so far from - alising such a ´´one-pot´´ operation that actual synthesis has to be achieved via a sequence of individual discrete steps. Thus, we are left with the task of planning each synthesis individually in an optimal fashion. Synthesis planning must be conducted with regard for certain speci - tions, some of which are due to the structure of the target molecule, and some of which relate to external parameters such as costs, environmental compatibility, or novelty. We will not consider these external aspects in this context. Planning of a synthesis is based on a pool of information regarding chemical reactions that can be executed reliably and in high chemical yield.
