| Abstract | |
This master thesis presents a general overview of the mass spectrometry technique coupled to vibrational ion spectroscopy, its applications, limitations, development and theoretical basis. For that, a summary of the quantum theory applied to vibrational spectroscopy, the nature of light, electromagnetism and optics of OPO/OPA, gas discharge and solid-state laser systems is shown. The experimental section is divided in two, the first presents the physical coupling of the mass spectrometer to the laser sources, along with softwares which allows the communication between these modules. In the second part, some IRMPD spectra of standard samples are presented for comparison and validation with the literature as well as unpublished spectra to exemplify the use of the ion spectroscopy technique in systems of biological interest, such as the DNA bases.
