This course covers various aspects of spectroscopy particularly, electronic spectroscopy of atoms, ions and complex molecules, vibrational, rotational and laser spectroscopy, as well as, spectral interpretation and analysis of samples using molecular spectroscopic tools. Terms symbols for free atoms and ions, spectroscopic interpretation of colours of complexes, and elementary molecular orbital theory will be discussed. Broadly speaking, it provides a general overview of the concepts of absorption, emission, vibration, rotation, resonance and electron spin. Instrumental methods to be covered in this course will include UV-Vis spectroscopy, fluorescence, infrared spectroscopy, Raman spectroscopy, nuclear magnetic resonance, and mass spectrometry.
