Colossal Magnetoresistant Materials: The Key Role of Phase Separation

Ranging from the physics of elementary particles to the structure of viruses, the subject matter of this book stresses the importance of optical activity and chirality in modern science and will be of interest to a wide range of scientists. Using classical and quantum methods with a strong emphasis on symmetry principles, the volume develops the theory of varied optical activity and related phenomena from the perspective of molecular scattering of polarized light. First Edition Hb (1983): 0-521-24602-4

Molecular Light Scattering and Optical Activity

ESR spectra of copper complexes have been interpreted by means of molecular orbital theory, and the ``covalent'' character of both σ and π bonds have been discussed for a variety of compounds. Overlap integrals have been considered in a consistent manner in treating σ bonds. Particular attention has been given to Cu phthalocyanine and several of its derivatives. The in‐plane π bonding may be as important in determining the properties of a Cu complex as is the in‐plane σ bonding.

ESR Studies on the Bonding in Copper Complexes

In this paper Crick, Brenner, and their collaborators described a very elegant series of genetic experiments by which they
 proved that the genetic code for protein was a triplet code. They used an acridine dye, proflavin, to induce mutations in
 a specific, well-studied gene of a virus, a so-called bacteriophage, that attacked the bacterium Escherichia coli. The effect
 of proflavin was to either eliminate a single nucleotide from the gene or to add a nucleotide, each of which had the effect
 of rendering the virus incapable of synthesizing a particular protein. After a sequence of three such additions or deletions,
 the nucleotide sequence of the gene once again come into frame, and synthesis of the protein resumed. This proved that the
 nucleotide sequence which carried the genetic information was to be read three (or, less likely, six) nucleotides at a time
 proceeding from a fixed starting point.

General Nature of the Genetic Code for Proteins

X-ray absorption Fe−K edge data on ferrous and ferric model complexes have been studied to establish a detailed understanding of the 1s → 3d pre-edge feature and its sensitivity to the electronic structure of the iron site. The energy position and splitting, and intensity distribution, of the pre-edge feature were found to vary systematically with spin state, oxidation state, geometry, and bridging ligation (for binuclear complexes). A methodology for interpreting the energy splitting and intensity distribution of the 1s → 3d pre-edge features was developed for high-spin ferrous and ferric complexes in octahedral, tetrahedral, and square pyramidal environments and low-spin ferrous and ferric complexes in octahedral environments. In each case, the allowable many-electron excited states were determined using ligand field theory. The energies of the excited states were calculated and compared to the energy splitting in the 1s → 3d pre-edge features. The relative intensities of electric quadrupole transitions...
