13 C chemical shifts and 31 P, 13 C spin‐spin coupling constants are reported for six model phosphinates and eight synthetic phosphinolipids. The complex spectra of the synthetic phosphinolipids could be assigned from increments and couplings derived from the model compounds. Based on these investigations the 3 J (PC) couplings of 7–15 Hz indicate a preferential trans orientation of the respective head‐group carbon relative to the phosphorus. This behaviour is similar to that of natural phosphatidylcholine lipids.
