The applications of a recently built Fourier Transform ion cyclotron resonance spectrometer are illustrated in this article. Present studies at the Institute
of Chemistry in São Paulo include: (a)the use of the high resolution capability to distinguish ions of different chemical composition but of the same nominal m/q; (b)the use of the ion trapping properties to study the kinetics of ion/molecule reactions; (c) the study of negative ion/molecule reactions of fundamental interest to organic chemistry; and (d)the ability to undertake photodissociation spectroscopy as a means to probe the electronic spectra of ions.
