- . EIMS reveals how ligands respond to electron irradiation; simple molecules such as CO and CO2 detach cleanly, making them “favorable” in FEBID. In contrast, anionic or polyhapto ligands, such as cyclopentadienyl (Cp) or allyl fragments, readily fragment form CxHy matrices, leading to film contamination
