2D SECSY experiment
(magnitude mode)
PRELIMINARY SET-UP
    • PARAMETER SET
    a 2D 1H-1H COSY-45 spectrum with rpar COSY45SW all and change the pulse program to secsyqf
    MODIFY SPECIFIC PARAMETERS

    Set nd0 to 2.

    Modify o1p and 2 sw values accordingly. 1 sw can be set to a smaller value (2-4 ppm) because cross-peaks are displayed about an axis of 135 degree relative to F1=0 Hz axis. For instance,

        o1 1700 (enter)
        2 sw 8 (enter)
        1 sw 3 (enter)

    On the other hand, the values of TD2 and TD1=NE are set, by default, to 1K and 128w, respectively. The SECSY experiment allows to use a more reduced data matrix by reducing TD1=NE. Finally, set the number of scans as a function of the sample concentration (by default, ns 8 and ds 4).
