The Physical and Theoretical Chemistry of Oxygen
1968Oxygen, which is the subject of this symposium is probably created during the helium-burning phase of stars. The nuclear reactions involved in the production of the three stable isotopes of oxygen are shown in Fig. 1. The stepwise reactions in which O16, O17 and finally O18 are produced probably occur at temperatures of the order of 108 degrees Kelvin ...

Theoretical studies in the chemistry and physics of heterocycles
Theoretica Chimica Acta, 1966LCAO-SCF calculations with four different sets of parameters are given for the π-electron structure of pyrrole. The aim was mainly to discuss whether such a kind of calculations could account for the molecular properties, or the σ system ought to be explicitly included. The effects of different values for the integrals were discussed by comparing final

Some theoretical problems in chemistry and physics
International Journal of Quantum Chemistry, 2006AbstractRecently the need for incorporating so‐called Jordan blocks in the theoretical formulation of dynamical processes in Nature has been confronted and challenged. In addition, quantum mechanics has evolved from the very theoretical to the highly technological prompting the establishment of the new field of quantum technology. Initial studies in an

Ανάπτυξη της Φυσικοχημείας: Θεωρητική και Πειραματική Προσέγγιση
2014Definition, classification and proof constitute the trilogy of methods of development and systematic presentation of Physical Chemistry. Through definition we disclose the logical comprehension of a concept and therefore we make it clear. Through classification we delimit the logical extension of a concept and therefore we make it perspicuous.

Variational Principles and Methods in Theoretical Physics and Chemistry
2002This book brings together the essential ideas and methods behind applications of variational theory in theoretical physics and chemistry. The emphasis is on understanding physical and computational applications of variational methodology rather than on rigorous mathematical formalism.

Exploring the Chemistry of Re(I): Physical and Theoretical Investigations
2015The development of Rhenium I photocatalysts has been pursued since Lehn first showed the excellent performance of the ReI bipyridine tricarbonyl catalyst. Since then, devel- opment has modified the organic ligand to demonstrate continued or improved activity with other α-diimine bidentate geometries.
