Theories of the chemical bond This is definitely any chemist's bible. It's co-authored by J. N. Murrell, J. M. Tedder and S. F. A. Kettle 3 british professors. According to them the book aims "to bridge the gap between the semi-qualitative description given in Coulson's Valence and the formal mathematical description given in Walter, Eyring and Kimball's Quantum Chemistry". Indeed it has that and much more. It approaches bonding theories in an accessible and friendly way. From the electronic theories of pi delocalization in organic compounds, such as the Huckel method, to which it devotes a whole chapter to the crystal field and ligand field theories for an approach to the description of inorganic compounds it contains some serious and still accessible introduction to Quantum Chemistry and its formal language demonstrating nearly every step necessary to a good understanding of the matter. Excellent drawings and schematics combining rigour with visualisation. A must have ! Note: my copy is from 1964 and therefore the review regards this print.
