Book excerpt: The behavior of substances in solutions may not be adequately characterized by the effect of any single physicochemical parameter of solvents, nor are numerous semi-empirical scales of the solvent effect (their ‘polarity’) suitable for their limited selections only. In recent decades, it has been found that the variation of reaction rate constants in solutions or that spectral parameters of dissolved substances are determined by the total effect of different solvation processes. This monograph presents numerous examples of such an approach and characterizes various empirical and semi-empirical scales of solvent properties. It is shown that additional consideration of some structural parameters of solvents, namely, their cohesive energy and the molar volume, may provide for spreading this approach on homolytical and catalytic reaction. It is also shown that for the solvolysis reaction, one of the excessive reagents may represent either a reagent or a solvent, which requires additional consideration of its structural characteristics in the Hammeth equation. The application of the principle of free energy linearity also allowed adequate generalization of data on the effect of solvents on different physicochemical processes, such as dissolution of gases and solids in various solvents, swelling of polymers and solid fossil fuels, coal extraction, adsorption, absorption, diffusion, and chromatography. Special attention is paid to substance distribution between two immiscible phases. Properties of both an extractive phase and an active extractant dissolved in inert diluter are taken into account. The majority of these processes indicate the efficiency of solvent self-association factor that defines the energy consumption for formation of a void for an alien molecule injection.

Available in PDF, EPUB and Kindle. Book excerpt: This book, Correlation Analysis in Chemistry: Recent Advances, is a sequel to our Advances in Linear Free Energy Relationships. t The change in the title is designed to reflect more accurately the nature of the field and the contents of the volume. The term LFER is still widely used, but it is often applied rather loosely to correlation equations that are not LFER in the restricted sense of a relationship involving logarithms of rate or equili brium constants on each side of the equation. The term "correlation analysis" seems to us more appropriate for the whole subject. The use of this term has compelled us also to introduce "chemistry" into the title; we have preferred not to prefix this with "organic" on the grounds that several areas of interest are not "organic chemistry" as usually understood, al though, of course, traditional applications of the basic relationships asso ciated with the names of Hammett and of Taft continue to be of interest. In the first volume we sought through our authors to provide a series of general articles covering the various aspects of the field as they seemed to us. Since the book was the first international research monograph in its field, each chapter, while giving prominence to recent developments, did not neglect earlier work, so that each article presented a comprehensive account of its own area.

Download or read book Chemometrics based Spectroscopy for Pharmaceutical and Biomedical Analysis written by Hoang Vu Dang and published by Frontiers Media SA. This book was released on 2019-04-17 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemometrics is the application of mathematics and statistics to chemical data in order to design or select optimal experimental procedures, to provide maximum relevant information, and to obtain knowledge about systems under study. This chemical discipline has constantly developed to become a mature field of Analytical Chemistry after its inception in the 1970s. The utility and versatility of chemometric techniques enable spectroscopists to perform multidimensional classification and/or calibration of spectral data that make identification and quantification of analytes in complex mixtures possible.Wavelets are mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale. They are now being adapted for a vast number of signal processing due to their unprecedented success in terms of asymptotic optimality, spatial adaptivity and computational efficiency. In analytical chemistry, they have increasingly shown great applicability and have been preferred over existing signal processing algorithms in noise removal, resolution enhancement, data compression and chemometrics modeling in chemical studies.The aim of this Research Topic is to present state-of-the-art applications of chemometrics, in the field of spectroscopy, with special attention to the use of wavelet transform. Both reviews and original research articles on pharmaceutical and biomedical analysis are welcome in the specialty section Analytical Chemistry.

This book was released on 2022-07-25 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum chemistry uses the Schrödinger equation to predict properties of molecules and their course in chemical reactions. From the 1920 to 1960s, it handled the complicated mathematical equations of quantum mechanics for molecules. Now, it can solve complicated problems through computer technology. It also makes real-time calculations with new concepts and simplifications. Novel approaches will be needed in quantum chemistry to promote research field beyond a set of techniques available in computer programs for showing many pressing problems of humanity. Currently, it is available to everyone to use popular free chemistry software packages. First generate new ideas to explore and produce truly novel results with their capabilities. Since 1960, remarkable advances are observed in the development and availability of computers for making all-important contributions to the solutions of critical problems in chemistry. One of the most challenges in chemistry is the prediction of the folded structure of peptide and protein synthesis in different chemical environments. It is highly interdisciplinary field of research, linking biology and biochemistry fields, like analytical, inorganic, organic, medicinal, physical, pharmaceutical and theoretical chemistry.
