Development of decision-making competence in courses of spectrometric analysis of organic compounds

Resumo

The aim of the present study was to develop a level of competence that is not normally found in graduate or post-graduate chemistry courses, through a didactic intervention in the discipline of spectrometric analysis of organic compounds. The methodology of the work consisted in the analysis of a sample of a compound unknown individually by each student. Whereas organic compounds spectroscopy is most often learned and practiced, this intervention allows students to become comfortable with ¹H and ¹³C NMR, and IR spectroscopy, in addition to mass spectrometry. Throughout the didactic intervention the students, through a thematic seminary, presented the results of the analysis of the spectra from the different techniques used. With the skills acquired from completing this laboratory work, the students become well-prepared to perform spectroscopic analyzes in subsequent experiments encountered in the organic chemistry laboratory.
