What is the distance, in Hz, between the two protons in the F2 dimension?

Hello Rodri,

I added the instrument frequency to the image.

For this situation you must be correlate with DEPTH-135 to 13-carbon and confirm that whether it belongs to CH or CH2.

Thanks for the info on the spectrometer frequency.
With that info, it seems to me that the two protons cannot be attached to the same carbon. Typically, a geminal J1(H-H) coupling is a large negative value, but not as large as the splitting we can see in this case (> 50 Hz?)

Cheers,
Rodri
