The crystal structure of the triclinic modification of vitamin A acid
C. H. STAM, Caroline H. MacGillavry · Acta Crystallographica · 1963
The crystal structure of the triclinic modification of vitamin-A acid has been determined from a sharpened three-dimensional Patterson synthesis and refined by three-dimensional least-squares methods.The all-trans-conjugated side chain is markedly curved in its plane because of the presence of the methyl groups.
