26. What is Inorganic Chemistry?

27. What is Inorganic Chemistry? “well, whatever it is, it starts with symmetry.” “… and what’s the big deal about this symmetry concept anyway?” “… and if symmetry is so important, why hasn’t it shown up by now?” Symmetry is the answer

28. Why is Symmetry useful? ~ for Spectroscopy ~ for Classifying Structure ~ for Bonding

29. Group Theory (as described by a physical chemist in some quantum text) 5. Group Theory (by a physical chemist whose name is forgotten) The subject of this chapter is one of the most enthralling within the domain of quantum mechanics, for not only does it simplify calculations, but also it reveals the underlying connection between apparently disparate phenomena. Whole regions of study may be unified in terms of its concepts. Angular momentum is a facet of group theory; so too are the properties of the harmonic oscillator. Turn the subject over and there appears the basis of the conservation of linear momentum and energy. Another facet classifiesthe elementary particles.; another illuminates the structure of transition metal complexes. The subject glitters with power and achievements, and one feels that (wo)man’s quest for understanding in terms of symmetry receives its vindication in Group Theory.
