Selective 1D NOESY experiment
PRELIMINARY SET-UP
  • Record a conventional 1H spectrum. Note the o1 of the selected resonance.
  • Perform the selective excitation on this selected proton resonance using a selective 270 degree pulse.
    • PARAMETER SET

    MODIFY SPECIFIC PARAMETERS

    If using a selective 270 degree pulse (p11), d14 is fixed to a minimum value of 20u. When using a selective 90 degree pulse (p11), this delay is optimized to (p11)/2 + d14 ~ 1/JHH

    The duration of the NOESY mixing time which is defined by a vd-list (l4 is the number of delays in this list). On the other hand, a fixed mixing time value can be specified.

    A minimum eigth scan cycle is needed (ns=8 and ds=4).
