Photoelectron Angular Distribution Measurements for Some Aliphatic Alcohols, Amines, and Halides

The angular distributions for the He I photoelectron spectra of some aliphatic alcohols, amines, and halides were measured in order to reexamine the assignments of the so-called p-type photoelectron spectral bands in the He I region of these molecules. The second band of methanol and the third band of ethanol were assigned to the in-plane n orbitals localized mainly on the oxygen atom. Furthermore, it was found that the angular distributions of photoelectrons were useful for the conformational analysis of molecules and that the sum of β values was conserved for these compounds.
