Abstract
L'INVENTION CONCERNE UN PROCEDE DE DETECTION SELECTIVE DE TRANSITIONS QUANTIQUES MULTIPLES EN RESONANCE MAGNETIQUE NUCLEAIRE. UN ETAT STATIQUE DE NON-EQUILIBRE D'UN ENSEMBLE DE RESONATEURS GIROMAGNETIQUES EST PREPARE. APRES UNE PERIODE D'EVOLUTION T, UNE IMPULSION DE MELANGE A 90 EST APPLIQUEE ET LA DECROISSANCE D'INDUCTION LIBRE EST ECHANTILLONNEE EN FONCTION DU TEMPS T. UNE FONCTION S (T, T, PH) EST DEVELOPPEE POUR DES VALEURS DE T MODIFIEES SYSTEMATIQUEMENT, ET DES VALEURS CHOISIES. DES COMBINAISONS LINEAIRES DE LA FONCTION S DONNENT APRES TRANSFORMATION DE FOURIER, UN SPECTRE BIDIMENSIONNEL DE TRANSITIONS QUANTIQUES MULTIPLES LIMITEES PAR LE CHOIX DES PHASES ET DES COMBINAISONS LINEAIRES. APPLICATION A LA SPECTROMETRIE.
