Unformatted text preview: CHEM 356, Lecture 1, Fall 2009 1 Our Understanding of Matter in 1900 ∙ it was understood from atomic theory that matter consists of atoms whose sizes and masses are known ∙ atomic theory plus laws of classical mechanics gave a kinetic theory of gases ∙ essential concept of the Periodic Table had been developed ∙ electrons had been identified, and were thought to be classical particles of specific size, mass, charge ∙ light was considered to be exclusively a wave phenomenon, all explainable in terms of Maxwell’s equations While much of the behaviour of matter had been explained by classical physics, there remained a number of experimental results that defied all attempts to explain them in terms of classical concepts. CHEM 356, Lecture 1, Fall 2009 2 Four Dilemmas of Classical Physics. 1. The distribution of blackbody radiation: observations. ∙ a completely black body at a uniform temperature had long been known to have the same distribution of frequencies of emitted/absorbed radiation independently both of the material making up its walls and of the shape taken by the body. ∙ the measured frequency distribution is found to depend solely upon the temper- ature, , of a blackbody Figure I.1. The temperature dependence of the distribution of thermal radiation from a blackbody cavity....
