Abstract The C4H10 molecule has been studied by high resolution (e,2e) spectrometer at a total energy of 1200eV and using symmetric non-coplanar kinematics. The binding energy spectra ranging up to 32eV are measured at out-of-plane azimuthal angles from 0o to 22o corresponding to target electron momentum from about 0.1 to 1.8 a.u. The binding energy spectra and electron momentum distributions obtained for the valence orbitals are compared with the theoretical result calculated by using restricted Hartree-Fock and density functional theory methods. The agreement between theory and experiment of orbital electron momentum distributions is generally good.
