Objetivos
This Unit/Subject has as main objective to deepen the concepts of chemical bond, presenting the spectroscopic techniques as a tool to observe the properties of the atoms, molecules and chemical bonds. This Unit/Subject will expand some of the themes introduced in the Unit/Subject "Química Geral"- General Chemistry. Chemical bond will be explored/studied as an extension of the atom properties, including an initial computational approach. An introduction to thermodinamics is also included. Absorption spectroscopies will be presented in close relation to the structural characteristics that they enlighten; mass spectrometry and nuclear magnatic resonance are shown as structural analytical tools in correlation with absorption spectroscopies and in parallel with compultational approaches usually used to solve and model structures.
Resultados de aprendizagem e competências
During the Unit/Subject "Espectroscopia Molecular"- Molecular Spectroscopy, the students shall be able to interpret several types of Spectra and correlate the spectra with the structures of the studied compounds.
They shall use the kwowledge previously acquired in General Chemistry and Organic Chemistry and complete it with the knowledge acquired focusing on the diffrent types of Spectroscopy.
