Based on the argument that the needs of chemistry are distinctive, a mathematical structure of topics such as quantum mechanics, relativity theory, thermodynamics and statistical mechanics, suiting the needs of chemistry, is outlined. The author adopts a practical approach and topics are arranged sequentially, from the mathematical basis through to general concepts. The book focuses on the new mathematical concepts that enable the exploration of interactions between particles, waves and fields within a chemical context, and is packed with examples to support its arguments. One of the greatest challenges in the field of molecular physics is the still outstanding measurement of the parity violating energy difference ΔEpv which electroweak theory predicts to exist between the enantiomers of chiral molecules. It differs from what is conventionally emphasized because of the different approach that it argues for the recognition of chemistry as an emergent discipline, ultimately based on the properties and structure of space and time. Many new developments, related to the interpretation and importance of symmetry relationships, quantum mechanics, general relativity, field theory and mathematics have occurred in the second half of the 20th century without having a visible impact on chemical thinking. An essential reference source, this book is suitable for physicists, theoretical and physical chemists, as well as students and researchers working in the field.

Centre for the Advancement of Scholarship. He was appointed lecturer in Chemistry at the University of the Orange Free State from 1958 to 1960. The book focuses on the new mathematical concepts that enable the exploration of interactions between particles, waves and fields within a chemical context, and is packed with examples to support its arguments. Molecular parity nonconservation caused by the parity violating property of the electroweak force is discussed. Different approaches to the computation of these parity violating influences are outlined and recent predictions for parity violating effects in spectroscopically and biologically relevant molecules are reviewed. He became a professor of at the and Extraordinary Professor at. But as this study reveals, there are good reasons to believe that compounds which are chiral in an electronically excited state are particularly suited for a possible proof of molecular parity violation.

Besides two-electron orbit-orbit and spin-spin coupling contributions, the Breit interaction gives rise to the spin-other-orbit coupling term of the Breit-Pauli Hamiltonian. He was visiting professor at the in 1994, and at the , in 1998, 2005, 2006, 2007 and 2010. An essential reference source, this book is suitable for physicists, theoretical and physical chemists, as well as students and researchers working in the field. The book is self-contained and can be used without reference to other sources. From United Kingdom to U. Faculty of Natural and Agricultural Sciences. He lectured as professor of chemistry and was Head, Department of Chemistry at the from 2000 to 2004.

Re-examines basic theories, such as electronegativity and electron spin, and introduces new theory Full of practical experiments and examples Is an excellent single reference source. His book Number Theory and the Periodicity of Matter co-authored with Demetrius C. The book focuses on the new mathematical concepts that enable the exploration of interactions between particles, waves and fields within a chemical context, and is packed with examples to support its arguments. He died on 28 August 2015 in Broederstroom, North West, South Africa after returning home from a crystallography conference. Show more Theories of Chemistry reviews the theories that underpin chemistry, but yet are not traditionally recognized as such, being normally considered as part of physics. The subject matter is arranged in a sequence that reveals the foundations of chemistry. The author adopts a practical approach and topics are arranged sequentially, from the mathematical basis through to general concepts.

Summary Many new developments, related to the interpretation and importance of symmetry relationships, quantum mechanics, general relativity, field theory and mathematics have occurred in the second half of the 20th century without having a visible impact on chemical thinking. The subject matter is arranged in a sequence that reveals the foundations of chemistry. By re-examining basic theories, The New Theories for Chemistry aims to introduce a new understanding of old concepts, such as electron spin, The Periodic Table and electronegativity. They had three children, Jan, Aletta and Larisa. In 1976 he was a Visiting Researcher at the , England.

He was also a strong believer in practical work to obtain tangible results over theoretical calculations: All advances in chemistry happen at the bench, as it should, but without the theoretical understanding, even of common events such as intramolecular rearrangement. University of the Free State. Based on the argument that the needs of chemistry are distinctive, a mathematical structure of topics such as quantum mechanics, relativity theory, thermodynamics and statistical mechanics, suiting the needs of chemistry, is outlined. It differs from what is conventionally emphasized because of the different approach that it argues for the recognition of chemistry as an emergent discipline, ultimately based on the properties and structure of space and time. Starting from the mathematical basis, the sequence runs through the general concepts mechanics and wave formalism and the elementary building blocks, to molecules and macrosystems. By re-examining basic theories, The New Theories for Chemistry aims to introduce a new understanding of old concepts, such as electron spin, The Periodic Table and electronegativity.

The book is the product of the author's reading of original literature rather than of standard texts. By re-examining basic theories, The New Theories for Chemistry aims to introduce a new understanding of old concepts, such as electron spin, The Periodic Table and electronegativity.

An essential reference source, this book is suitable for physicists, theoretical and physical chemists, as well as students and researchers working in the field. The importance of the Breit interaction for an accurate prediction of parity violating energy differences between enantiomers is studied within electroweak quantum chemical frameworks. No calculation can predict chemical reactions.

Elementary matter is assumed in both theories to occur as zero-dimensional point particles. Boeyens 1934-2015 was a South African and educator. The E-mail message field is required. May not contain Access Codes or Supplements. An essential reference source, this book is suitable for physicists, theoretical and physical chemists, as well as students and researchers working in the field.

This monograph argues against this proposition primarily on the basis of the two theories' incompatibility and of some untenable philosophical implications of the quantum model. Here, first calculations of the parity violating energy difference in electronically excited states are presented and routes to its measurement are discussed.

Hence the emphasis on otherwise unexpected topics such as quaternions, lie groups, polarized light, compressed atoms, rydberg atoms, solitons, molecular hydrogen, and phase transitions, amongst others. Many new developments, related to the interpretation and importance of symmetry relationships, quantum mechanics, general relativity, field theory and mathematics have occurred in the second half of the 20th century without having a visible impact on chemical thinking.
