Many molecules can rotate internally around one or more bonds so that during 360°'s rotation, they will change between unstable and relative stable conformers. The internal rotation of molecules can lead to much different electron density distributions for certain molecular orbitals (MOs). By comparing the measured electron momentum profiles with the calculated ones, the relative stability of different conformers of 1-butene has been determined, demonstrating that the electron momentum spectroscopy (EMS) is a feasible experimental method to study the conformational preference of molecules.
