Abstract in Portuguese
Neste trabalho apresentamos a construção de um Espectrômetro de Ressonância Magnética Nuclear (RMN) de Banda Larga, operando a freqüência fixa de 21 MHz. O resultado da determinação do teor de óleo em grãos de milho e apresentado. r discutida uma metodologia que pode ser empregada num programa de seleção individual de grãos de milho, com o objetivo de aumentar ou diminuir seu teor de óleo. r apresentado também os resultados do acompanhamento de reações de polimerização em função do tempo, usando a técnica de RMN

Abstract in English
This work presents a wide-line Nuclear Magnetic Resonance (NMR) spectrometer, operating at fixed frequency of 21MHz. This instrument was build at the Instituto de Física e Química de são Carlos, USP. Results with the oil content of corn-seed is presented. We present also a discussion of a methodology suitable for a program of breeding corn for increased or reduced oil content. The study of the decrease of signal amplitude as a function of time for some polymers is also presented
