The 1 H (500 MHz), 13 C (300 MHz) and 31 P (202 MHz) NMR spectra of rac ‐2,3‐bis(palmitoyloxy)propyl(2‐trimethylarsonioethyl)phosphonate were recorded in CDCl 3 (3 M) solution. Homonuclear 1 H‐ 1 H and heteronuclear 13 C– 1 H chemical shift correlation experiments (COSY) were performed. All resonances were assigned. The shifts of the arsenic‐containing phosphonolipid were compared with the shifts of the N ‐containing phospholipids. The most significant shift differences were found for the groups directly bonded to arsenic. Spectral evidence was indicative of free rotation about the CH 2 CH 2 bond in the arsenocholine fragment.
