Double layers are formed by α,ω‐docosanediol (C 22 diol) when it is spread on a water surface. The space group (a slightly relaxed form of P 2 1 / a ) and the lattice parameters of the unit cell were determined by X‐ray diffraction. Furthermore, multilayer formation was inhibited by addition of 10% of C 24 H 49 OH or 5% of HO(CH 2 ) 22 OCH 2 Ph to the spreading solution. The coverage with the double layer was reduced to less than 15%; the rest was occupied by a monolayer.
