Angular distribution and energy spectra of photoelectrons from tetrahydrofuran illuminated by VUV photon source

Photoelectron emission from the valence shell of biologically relevant tetrahydrofuran (THF) molecule is studied. Energy and angular distributions of photoelectrons from THF ionized by a He(I) vacuum ultraviolet (VUV) photon source are measured. Theoretical calculations performed for the binding energies of orbitals and photoelectron intensities are in reasonable agreement with measurement. The observed angular distributions show the determining role of dipole transition mechanism. •Tetrahydrofuran illuminated with a vacuum ultraviolet photon source.•Energy and angular distribution of photoelectrons from tetrahydrofuran.•Calculated and measured angular distribution of photoelectrons from tetrahydrofuran.
