Single-molecule manipulation using scanning probe microscopy has long provided a model system for studying nanoscale friction, yet the accompanying energy dissipation processes remain less understood. Here, we investigate the manipulation of a CO molecule on Cu(110) using STM, AFM, LFM, and DFT simulations under cryogenic and ultra-high vacuum conditions. DFT predicts tip-height–dependent adsorption site transitions, which are supported by experimental signatures from IETS and dissipation signals. While AFM reveals dissipation along specific manipulation paths, LFM uncovers additional dissipative trajectories associated with molecular switching events. These findings provide new insight into frictional dissipation mechanisms and highlight LFM as a valuable tool for probing energy landscapes in atomically resolved molecular manipulation.
