Learning outcomes IIn this curricular unit it is intended that the student acquires knowledge in the field of structural analysis of organic compounds, with known or unknown structure, using various spectroscopic techniques, in particular, IR spectroscopy, UV-vis., H NMR, C and Two-Dimensional and mass spectrometry. At the end of this CU students must: -Know the fundamentals of different spectroscopic techniques; -In IR spectroscopy, know the interactions and types of connections that produce the different absorptions and identify functional groups; -In UV-vis spectroscopy, define the different absorption systems, chromophores, conjugated systems and aromatic; -Apply H-NMR and C. Know what is chemical shift and splitting of the signal; -Apply two-dimensional correlation-H - H, H - C, for structural determination; -Know mass spectrometry and the concepts molecular ion, molecular formula, base peak and fragmentation; -Apply the different methods for structure assignment.
Syllabus 1 - Spectroscopy UV / Vis.: Introduction; Sample preparation and registration of the spectrum; Chromophores; Applications of Spectroscopy UV / Vis.; Spectroscopy derived. 2 - IR Spectroscopy – Raman: Introduction; Fundamentals and selection rules; Preparation of samples. The IR spectrum: Characteristic absorptions; Absorptions of bonds in organic molecules; IR Spectroscopy quantitatively. Raman Spectroscopy. 3 - NMR spectroscopy: Physical Fundamentals; NMR spectra and molecular structure; NMR spectroscopy H; Spectroscopy 13 C-NMR; Methods of Correlation, two-dimensional NMR. 4 - Mass spectrometry: Introduction; Fragmentation of organic compounds, the main reactions; Ionization methods; Methods of analysis.

Teaching Methodologies and Assessment Criteria The assessment will be divided as follows: 1) 1 Knowledge assessment test (60%), (over all given subject) 2) 1 Individual seminar on a UC Theme (10% for the report + 10% for the discussion), (theme to be chosen by the students or the Professor) 3) Practical classes (attendance (5%) + participation in the work (5%) + treatment of results (10%)).
Language Portuguese. Tutorial support is available in English.
