He I UV photoelectron spectra of four naturally occurring polyenes were measured. The spectra were interpreted on the basis of empirical arguments and semiempirical MO calculations. The results show that through-bond interactions between π-orbitals are discernible in spite of the non-rigid molecular geometry. This work shows that natural products have electronic structures which are of interest to a wider circle of chemists than just those who specialize in natural products.
