1. The document discusses principles of spectroscopy, including absorption spectroscopy which measures light absorbed by a sample (e.g. UV-Vis, IR, NMR) and emission spectroscopy which measures light emitted from an excited sample (e.g. fluorescence, Raman spectroscopy). 2. It covers electronic transitions in molecules, character tables, determining symmetry of molecular orbitals, and which transitions are allowed. Singlet and triplet states are also discussed. 3. Advantages of fluorescence spectroscopy are highlighted, including high sensitivity down to the microgram level and specificity from characteristic excitation and emission wavelengths. Examples of applications to inorganic analysis of metals and anions are provided.
