Chemical bond stands as the alpha-and-omega of Chemistry: it is at the beginning because, according with International Union of Pure and Applied Chemistry-IUPAC, a bond exists between two atoms or groups of atoms when the forces acting between them lead to an aggregation with sufficient stability to be considered as molecular species; it is also at the end due its mysterious way of acting through electronic behavior that is comparable with nothing of the observed world. The fact that two electrons, which in principle repel each other as they approach, can exist in a certain molecular space providing the atoms-in-molecule binding - that is still an unfolded reality. Nevertheless, quantum theory had furnished the main analytical tools with which the so called ordinary chemistry reduced at the many-electronic problem, a field equally belonging to quantum physics and quantum chemistry. After the impressive success of quantum theory in explaining atomic structure and spectra starting from the complete analytical solution of Hydrogen atom, and after the further quantum extensions of models to include the elucidation of simple molecules, the Chemistry arrives today in front of new challenges: nano- and bio-systems. At this point it seems that there is no chance to provide fully analytical results with the myriads of electrons in macro-molecules. Moreover, even one could admit that the computational techniques will evolve sufficient to deliver numerical results these will certainly suffer of opacity in interpretation loosing the most beloved issue of chemists: the intuition. At the same time, there are also relatively small molecules with particular bonding features, since bonds in which there are no shared electrons between atoms - at one extreme - or molecules with a sextuple bond - at other extreme - may be identified. As a consequence, the increased need of molecular design for assessing nano- and bio- targets through active ligands, the practical demands of predictions of acute toxicity in medicine and ecotoxicology - all these actual realities of chemistry in its principles and applications, call for dedicated reviews. In such theoretically demanded context of conceptual and computational chemistry the present review book likes to give a survey of the quantum physical chemistry and of its application in chemical bond and bonding description. Through the chapters of this book ones of the leading scientists in both physical and chemical fields have gave their valuable contributions for decrypting the actual status quo of the chemical bond and bonding: from self-consistent equations of many-electronic systems, localization, and reactivity principles, to coherent electronic states, to non-covalent bonding and overlapping concepts, to hydrogen and biomolecular bonding, to molecular connectivity and topological indices, to oscillatory quantum states of molecules, to carbon and pseudohalide bonding, to three-center bonding problem, to biochemistry, to medicine, and to ecotoxicology chemical bonding implications. It is therefore a comprehensive volume of physical and chemical quantum approaches of molecules grasping various conceptual and computational levels. It is also an invitation to reflect upon the possibility of unifying the physical and chemical quantum concepts in a novel alchemy of molecular structure. In this respect worth, finally, recalling that the author of Philosophia Naturalis Principia Mathematica was, at his time, proudly considered himself merely as an alchemist, and that his corpuscular vision about light was based on revealed concept of sympathy . From sympathy to bond and bonding it appears that the actual Chemistry and Physics continue to offer fascinating mysteries to humankind of which the elucidation of the nature of the chemical bond being, perhaps, the greatest one.

The concept of a chemical bond evolved from a variety of experimental observations. It became useful to understand, at times even predict, the molecular structure, reactivity and mechanism of chemical reactions. Every aspect of the concept of bonding received a quantitative interpretation from the advent of quantum mechanics and its application to chemistry.In Lectures on Chemical Bonding and Quantum Chemistry the reader will find a comprehensive discourse on the basic interpretation of the chemical bond as well as current understanding in terms of a 'dancing' molecule that not only travels, rotates and pulsates around an equilibrium molecular structure, but also interacts and collides with other molecules, thereby transferring linear and angular momentum characteristics and adjusting total energies. One will also find a thorough survey of quantum mechanical methodologies for calculation of molecular characteristics in specific states and their changes under spectroscopic transitions, tunneling, electron and proton transfer phenomena, and so on. Guides to more advanced levels of theory are also provided.
