✦ Synopsis

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 throughbond interactions between p-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.

UV photoelectron spectra were measured for poly( 1,l '-ferrocenediyl) (PF) synthesized in a well controlled way. The spectra are similar to those of ferrocene and I, 1 '-biferrocene, indicating limited electron delocalization. The ionization threshold energy was found to be 5.1 eV. Comparison with r
