Jens Peder Dahl was closely associated with Carl s research group for many years, and his introductory chapter summarizes his scientific achievements and in particular his contributions to the inorganic renaissance which unfolded from 1950. Harry Gray recounts his very fmitful collaboration with Carl which resulted in a general molecular orbital description of the metal-oxo bond, and he and Jay Winkler review more recent experimental and spectroscopic data on metal-oxo complexes of the later transition metals. Colin Flint also provides a brief review of... 

This review is dedicated to the memory of Carl Johan Ballhausen, our scientific grandfather so to speak. We have both received our formal training in quantum chemistry from Jens Peder Dahl, a former graduate student of Ballhausen, and one of us (NEH) was personally introduced to Carl Johan Ballhausen around 1980 - at that time already the grand old man of quantum chemistry in Denmark. Towards the end of his scientific career - after his seminal contributions to the theory of chemical bonding - Carl Ballhausen considered various nonstationary time-dependent problems in molecular quantum mechanics. That is, topics which are related to this review and to the dynamics of the chemical bond. 

During the year 2000, two Lowdin Lecturers were invited Professor Roy McWeeny, Pisa, Italy, and Professor Jens Peder Dahl, Copenhagen, Denmark. They both agreed to deliver their lectures during QSCP V. Due to unforeseen circumstances, only one lecturer could attend QSCP V. The second lecture was therefore presented half a year later and then as the Ldwdin Memorial Lecture. Both are published as introductory chapters of the two proceedings volumes as a joint tribute to a great leader and pioneer in quantum chemistry. We are very proud to present QSCP V New Perspectives in Quantum Systems in Chemistry and Physics, in the series Advances in Quantum Chemistry, founded by Lowdin. 

In Chapter 5, John Avery and Jens Peder Dahl give elegant treatments of the D-dimensional hydrogenic atom, both in direct and in momentum space. Here we consider only a few elementary properties. With V(r) = 1/r in Eq.(9), these properties are readily derived from D = 3 results by exploiting the isomorphism of Eq.(lO). This gives the energy levels as...
