• Record a ¹H spectrum.

a conventional 1D ¹H-¹³C HMQC spectra with rpar HMQC1D all and change the pulse program to hsqcgpnd1d that

d2 is the evolution delay d4 is optimized to 1/(4*¹J_CH) and, by default, set to 1.17 ms (for CHCl₃).

Finally, gradient parameters must be defined. Standard values can be:

gpnam1=gpnam2=gpnam3=SINE.100
gpz1=80
gpz2=30
gpz3=20.1
p16=1ms
d16=100u

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