^13^C{^1^H} single frequency off‐resonance decoupled spectra of secondary carbons with two chemically non‐equivalent protons are analysed theoretically and experimentally. By a careful analysis of the frequencies of all six transitions all spectral parameters, including the geminal proton‐proton coupling constant, can be determined very accurately.
