• Record a ¹H spectrum.

a conventional 1D ¹H-¹³C HMQC spectra with rpar HMQC1D all and change the pulse program to indecord1d that

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

The 1H p0pulse is set accordingly to the carbon multiplicity editing:

60 degree - XH positive, XH2, XH3 negative

90 degree - XH2 only

120 degree - XH3 positive, XH, XH2 negative

180 degree - XH2 positive, XH, XH3 negative

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