The integral intensities of the skeletal vibrations of the aromatic rings of 12 aporphine alkaloids have been measured. It has been established that with an increase in the twisting of the C1-C11 bond (cos Q) caused by the different natures of the spatial interaction of the 1,11-substituents ΣA decreases.
