how to get a 1H-15N HMBC spectroscopy

hi All,

I run a 1H-15N HMBC experiment on a Bruker AVANCE III 600 MHz spectrometer. But I fail to get the long- range correlation signal. please help me to set the acquisition parameters of the 1H-15 HMBC experiment, especially the “cnst2” (J(XH)) and the “cnst13” (J(XH) long range), or other key parameters.

Thank you very much!
