Class notes for Chapter 2: Quantum-Mechanical Model in the class General Chemistry: Macroscopic Investigations and Reaction Principles (CHEM 130) at the University of Michigan. Subjects covered include wave natures of light and matter, electromagnetism, diffraction, the particle nature of light, Bohr model and de Broglie wavelength, and atomic orbitals.

Why is electronic structure important? - Answer All of chem is governed by transfer of electrons or the arrangement of electrons. How do you study electronic structure? - Answer Use interaction of light with matter to study the electronic structure. Light - Answer a "wave of energy" that consists of oscillating electric and magnetic fields. Frequency - Answer number of complete cycles pf electric fields that pass a given point per second. Wavelength - Answer distance between successive ...
