Abstract
Dynamic behavior of cyclohexane adsorbed on Ni(111) under the irradiation of NIR pulses (1064 nm) was studied by time-resolved sum-frequency generation (SFG). Two types of adsorbed cyclohexane were observed on Ni(111), which were attributed to the ordered cyclohexane domains at high coverage and disordered cyclohexane molecules. When the surface was temporally heated up by the irradiation with the NIR pulses, the disordered cyclohexane molecules were thermally excited to form the ordered structure.
