SUPRESSAO DAS ANOMALIAS DE FASE E BATIMENTOS LATERAIS EM ESPECTROS DE RMN ~(13)C OBTIDOS COM A SEQUENCIA DE PRECESSAO L1VRE NO ESTADO ESTACIONARIO

摘要

The Steady-State Free Precession (SSFP) sequence has been widely used in low-field and low-resolution imaging NMR experiments to increase the signal-to-noise ratio (s) of the signals. Here, we analyzed the Scrambled Steady State - SSS and Unscrambled Steady State - USS sequences to suppress phase anomalies and sidebands of the ~(13)C NMR spectrum acquired in the SSFP regime. The results showed that the application of the USS sequence allowed a uniform distribution of the time interval between pulses (T_p), in the established time range, allowing a greater suppression of phase anomalies and sidebands, when compared with the SSS sequence.
