satellites

 

In this example, we see a signal for a nucleus that is coupling to:

• 1 x nucleus A with I = 1/2 and 100% natural abundance, to give a doublet with J_main
• 1 x nucleus B with I = 1/2, but with a natural abundance that can be altered to X%, to give doublet satellites with J_satellites worth X% of the whole signal.

Use the sliders below to adjust the various parameters (Natural Abundance of nucleus B, and the coupling constants to each of the nuclei).
