研究领域

Mónica Barra's research projects focus on understanding fundamental thermodynamic and kinetic properties of organic systems of significance to the general field of materials science and of various potential uses, ranging from pharmaceutical applications and catalysis to sensors and microelectronics. Investigations are based primarily on the application of UV-visible absorption spectroscopy, fluorescence spectroscopy, and time-resolved laser-flash photolysis techniques. While the emphasis of our projects is on thermodynamic and kinetic properties, studies also involve organic synthesis, and thus the application of chromatographic techniques, mass spectrometry as well as NMR and IR spectroscopy.
