Unit cell dimensions of some long chain fatty acid polymorphs
Unit cell dimensions and space group assignments for several polymorphic fatty acids have been determined by using single‐crystal X‐ray precession photography. This technique is useful to distinguish the closely similar B‐ and E‐forms of stearic acid which have nearly identical crystal long spacings...

| Zusammenfassung: | Unit cell dimensions and space group assignments for several polymorphic fatty acids have been determined by using single‐crystal X‐ray precession photography. This technique is useful to distinguish the closely similar B‐ and E‐forms of stearic acid which have nearly identical crystal long spacings but significantly different unit cell dimensions and monoclinic angles. Other samples studied were the B‐form of arachidic and behenic acids and the unsaturated acids,trans‐9‐octadecenoic andtrans‐5‐eicosenoic. |
