CHEM1101 - Resources for Week 5
Topics and Learning Outcomes
Spectroscopy
relate absorption and emission of photons to changes in electron energy levels calculate emission and absorption wavelengths from energy levels identify constraints on analysis by atomic absorption spectroscopy (AAS) describe how the hollow cathode lamp operates, and why it is central to sensitive AAS measurements use the Beer-Lambert law understand the relationship between absorption and observed colour relate electronic absorbance and emission spectra to electronic structure recall the meanings of HOMO and LUMO, and determine the lowest energy electronic transition describe the process of molecular spectroscopy compare and contrast atomic and molecular spectroscopy calculate energy levels for one-electron atoms
Band Theory - MO in Solids
recognise that interactions of σ-orbitals gives rise to a valence bands, and σ* orbitals give rise to a conduction band in covalent networks use, define and explain the concepts of conduction band, valence band, band gap, hole, acceptor level, donor level, n -doping and p -doping explain the relationship between band gap and electrical and optical properties explain how n or p doping gives rise to conductivity of electrons and hole explain why the conductivity of semiconductors increases with temperature recognise a diagram of the band structure of insulators, metals and types of semiconductor.
recall that the number of molecular orbitals increases with the number of atoms in a molecule
