The protons labeled Ha in the structure below generally show up as a triplet, even through there are three neighboring protons. The coupling constant is approximately 7 Hz. What does this suggest about the size of the coupling constant for the aldehydic proton? 
Coupling Constant
A parameter in nuclear magnetic resonance (NMR) spectroscopy that measures the interaction between spinning nuclei.
Aldehydic Proton
The hydrogen atom attached to the carbon of an aldehyde group, which is typically more deshielded in NMR spectroscopy compared to other hydrogen atoms.
- Clarify the link between coupling constants and the magnetic setting of protons.
