Selective 1D COSY 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.

    MODIFY SPECIFIC PARAMETERS

    The delay for homonuclear coupling evolution is optimized to (p11)/2 + d14 ~ 1/(2*JHH) where p11 is the length of the selective 90 pulse and d14 must be fixed.

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

    PROCESSING
    Transform with and corrects the phase (peaks must present an anti-phase pattern).
