Mass spectra obtained upon ion‐beam‐induced desorption of homologic series of SAMs on Au(111) (see picture) show an odd‐even effect following odd‐even changes in the SAM chain length. By comparing the measured results with existing data obtained by other experimental techniques, a new methodology for tracing systematic changes in the stability of AuS and SC bonds in SAMs is demonstrated.
