• Record a ¹H spectrum.

a conventional 1D ¹H-¹³C HMQC spectra with rpar HMQC1D all and change the pulse program to hmqcnd1d that

d2 is the evolution delay d2 is optimized to 1/(2*¹J_CH) and, by default, set to 2.34 ms (for CHCl₃).

On the other hand, the following standard acquisition parameters can be modified: d1, ns, ds, sw and td.

Transform the recorded data with ef (lb=1) and phase the satellites in order to obtain an anti-phase doublet.
