The present subvolume provides evaluated data from HD¹⁶O, HT¹⁶O, HD¹⁷O, HD¹⁸O, and DT¹⁶O isotopologues. The introduction is intended to give a quicker access to the meanings of symbols found in the data tables. It reports molecular theories and equations, based on which most of the evaluated data given in the tables are established. These tables are preceded by an additional index in order to facilitate the search for specific information.

The tables report molecular constants and/or, below about 5000 cm ¹, assigned...

Conjugated polymeric materials and their nanocomposites are widely used for the creation of alternative sources of renewable energy, cell phone screens, mobile gadgets, video players and OLED-TV, as well as organic diodes, transistors, sensors, etc. with field-dependent and spin-assisted electronic properties. Multifrequency EPR Spectroscopy methods can help researchers optimize their structural, magnetic and electronic properties for the creation of more efficient molecular devices. This book will acquaint the reader with the basic properties of conjugated polymers, the fundamentals of...

The objective of this volume is to present a full and critical spectral data coverage of the entire major fields relating to tetraphenyl and analogous porphyrins, their precursors, catabolic derivatives, and related systems electronically.

The porphyrins are an important class of naturally occurring macro cyclic compounds that play a very important role in the metabolism of living organisms. They have a universal biological distribution and were involved in the oldest metabolic phenomena on earth. Without porphyrins and their relative compounds, life as we know it would be impossible...

This thesis reports studies on the substrate specificity of crucial ketosynthase (KS) domains from trans-AT Polyketide Synthases (PKSs). Using a combination of electrospray ionisation-mass spectrometry (ESI-MS) and simple N-acetyl cysteamine (SNAC) substrate mimics, the specificity of a range of KS domains from the bacillaene and psymberin PKSs have been succsessfully studied with regard to the initial acylation step of KS-catalysis.

In addition, the ability to alter the substrate tolerance of KS domains by simple point mutations in the active site has been demonstrated. A series of...

Annual Reports on NMR Spectroscopy provides a thorough and in-depth accounting of progress in nuclear magnetic resonance (NMR) spectroscopy and its many applications. Nuclear magnetic resonance (NMR) is an analytical tool used by chemists and physicists to study the structure and dynamics of molecules. In recent years, no other technique has gained as much significance as NMR spectroscopy. It is used in all branches of science in which precise structural determination is required, and in which the nature of interactions and reactions in solution is being studied.

This book...

Keeping abreast of the latest techniques and applications, this new edition of the standard reference and graduate text on laser spectroscopy has been completely revised and expanded. While the general concept is unchanged, the new edition features a broad array of new material, e.g., ultrafast lasers (atto- and femtosecond lasers) and parametric oscillators, coherent matter waves, Doppler-free Fourier spectroscopy with optical frequency combs, interference spectroscopy, quantum optics, the interferometric detection of gravitational waves and still more applications in chemical analysis,...

This lecture notes book presents how enhanced structural information of biomolecular ions can be obtained from interaction with photons of specific frequency - laser light. The methods described in the book "Laser photodissociation and spectroscopy of mass-separated biomolecular ions" make use of the fact that the discrete energy and fast time scale of photoexcitation can provide more control in ion activation. This activation is the crucial process producing structure-informative product ions that cannot be generated with more conventional heating methods, such...
