The hysteretic displacement of an SF₆ monolayer on graphite by Kr was studied using infrared reflection absorption spectroscopy supplemented by ellipsometry. The SF₆ molecule has a strong IR-active vibrational mode (ν₃) at 948.0 cm⁻¹. The coverage and local density of the SF₆ monolayer are inferred from the ν₃ absorption peak area and the blue shift of the ν₃ mode, respectively, the latter due to dynamic dipole coupling between SF₆ molecules in the layer. Throughout the temperature range 65.3 to 110.2 K, a first order transition with large hysteresis was found in the SF₆ monolayer displacement-recovery cycle driven by Kr spreading pressure. The hysteresis is asymmetric, with displacement going to completion at a sharp pressure, while the initial ~10% of recovery occurs much closer to the displacement pressure than the pressure allowing full recovery, especially above 95 K. Over the temperature range studied, an upper limit of 0.25% on the solubility of Kr in the SF₆ layer was determined by the absence of a significant change in the collective vibrational mode frequency preceding displacement. Above 92 K, spectra indicate a small solubility of SF₆ in the Kr monolayer, up to 4% approaching displacement of the Kr layer at T ≥ 98 K. Below 74 K the kinetics of SF₆ displacement to bulk is sufficiently slow that the monolayer is readily compressed to a metastable bilayer covering half the surface, with both layers apparently 2 × 2 commensurate with the graphite substrate. The decay time constant of the confined bilayer to bulk SF₆ crystallites is about 4 h at 65.3 K.
