associated with covalent bonds. A noncovalent contribution often called through‐space coupling (TSC) has been observed for heavy atoms. In this study, the TSC was detected and analyzed for the more common 1H1H coupling as well. In synthesized model molecules the hydrogen positions could be well controlled. For several coupling constants the through‐space mechanism was even found to be the predominant
