Notizen:
High-quality gradient-selective COSY spectra were recorded at 300 MHz for brucine and gibberellic acid and double-quantum filtered gradient-selective COSY spectra for brucine, using a single-frequency, high-resolution 1H probe modified by the addition of an unshielded z-gradient coil set. Data were efficiently recorded using buffered acquisition with a single transient per increment in 1t, in times much lower than those required for phase-cycled COSY, and with no loss of information. Gradient-selective COSY90, COSY45 and long-range COSY45 experiments, and the correlations leading to chemical shift assignments for gibberellic acid, are reported.
