1. Development of strongly modulated pulses for quantum information processing via Nuclear Magnetic Resonance / Utilização de pulsos de radiofrequência fortemente modulados no processamento de informação quântica via ressonância magnética nuclear
This dissertation presents the development and use of radiofrequency pulses simultaneously modulated in frequency, amplitude and phase (Strongly Modulated Pulses, SMP) for creating initial states and executing logical operations used as building blocks for Quantum Information Processing via Nuclear Magnetic Resonance (NMR-QIP). The experimental implementatio

2. 1H homonuclear editing of rat brain using semiselective pulses.
We have used a semiselective Hahn spin-echo sequence of the form (1331)-tau-(2662)-tau-AQ, delivered by a surface coil to obtain high-resolution 1H NMR spectra from the brains of intact dead rats. This sequence gave suppression of the tissue water resonance by a factor of 80,000 when tau = 68 ms. Delivery of a frequency-selective Dante pulse train to the alp
