Linear dichroism and molecular orientation in Langmuir-Blodgett films of plastoquinones and alpha-tocopherol quinone.
The linear dichroism of monolayers of plastoquinone-9, plastoquinone-3 and alpha-tocopherol quinone has been measured. The angle between the transition moments and the plane of the solid support was found to lie between 24 degrees and 28 degrees for the investigated prenylquinones. The possible orientation of quinone rings in a monolayer state has been discussed.
