Available in PDF, EPUB and Kindle. Book excerpt: Much of what we know about atoms, molecules, and the nature of matter has been obtained using spectroscopy over the last one hundred years or so. In this book we have collected together twenty chapters by eminent scientists from around the world to describe their work at the cutting edge of molecular spectroscopy. These chapters describe new methodology and applications, instrumental developments, and theory which is taking spectroscopy into new frontiers. The range of topics is broad. Lasers are utilized in much of the research, but their applications range from sub-femtosecond spectroscopy to the study of viruses and also to the investigation of art and archeological artifacts. Three chapters discuss work on biological systems and three others represent laser physics. The recent advances in cavity ringdown spectroscopy (CRDS), surface enhanced Raman spectroscopy (SERS), two-dimensional correlation spectroscopy (2D-COS), and microwave techniques are all covered. Chapters on electronic excited states, molecular dynamics, symmetry applications, and neutron scattering are also included and demonstrate the wide utility of spectroscopic techniques. Provides comprehensive coverage of present spectroscopic investigations Features 20 chapters written by leading researchers in the field Covers the important role of molecular spectroscopy in research concerned with chemistry, physics, and biology

Download or read book Theoretical Models of Chemical Bonding written by Zvonimir B. Maksic and published by Springer. This book was released on 2012-12-22 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: The renowned theoretical physicist Victor F. Weisskopf rightly pointed out that a real understanding of natural phenomena implies a clear distinction between the essential and the peripheral. Only when we reach such an understanding - that is to say when we are able to separate the relevant from the irrelevant, will the phenomena no longer appear complex, but intelectually transparent. This statement, which is generally valid, reflects the very essence ofmodelling in the quantum theory of matter, on the molecular level in particular. Indeed, without theoretical models one would be swamped by too many details embodied in intricate accurate molecular wavefunctions. Further, physically justified simplificqtions enable studies of the otherwise intractable systems and/or phenomena. Finally, a lack of appropriate models would leave myriads of raw experimental data totally unrelated and incomprehensible. The present series ofbooks dwells on the most important models of chemical bonding and on the variety of its manifestations. In this volume the electronic structure and properties of molecules are considered in depth. Particular attention is focused on the nature of intramolecular interactions which in turn are revealed by various types ofmolecular spectroscopy. Emphasis is put on the conceptual and interpretive aspects of the theory in line with the general philosophy adopted in the series.

Premadasa and published by . This book was released on 2020 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigating the specific local environment and molecular interactions at liquid surfaces is crucial in comprehending physical, chemical, and biological processes. Probing the interfacial molecular conformations will provide an insight into the relationship between surface structure and the governing interactions at the surface. Herein, this dissertation used the approach of the effect of substituents on the interfacial conformation of a methacrylate backbone, to observe such surface structure interaction relationships. The ethyl end of the methacrylate monomer was substituted with bulky groups and electron-withdrawing groups. These substituted monomers were synthesized via nucleophilic addition elimination reaction and characterized using sum frequency generation (SFG) spectroscopy at the air-liquid interface. The spectroscopic results were correlated with surface tension measurements and the overall dipole moment of the molecules. The presence of bulky substituents affected the orientation distribution of the interfacial molecules. On the other hand, in the presence of electron-withdrawing groups, the intensity of vibrational modes was affected, suggesting the changes in interfacial molecular conformations and existing intermolecular interactions. In another project, quaternary ammonium surfactants were utilized to assess their conformation and orientation at the air-water interface using SFG spectroscopy. Herein, the approach of solvent isotopic substitution was used to investigate the surfactant water interactions. The results showed the addition of deuterated water rearranges its head group parallel to the interface and straightens its chain with reduced gauche defects. The change in the conformation of the surfactant molecules at the air-liquid interface showcased the difference in intermolecular interactions for water and deuterated water. In summary, these studies revealed the importance of SFG spectroscopy as a tool to probe surface structures in gauging molecular interactions and physiochemical properties at the air-liquid interface.
