SFG measurements. (a) Schematic of the SFG apparatus using the pure rolling reciprocating rig, which is the same as the UTFI apparatus. (b) SFG spectra of SA/HD-d34 under static and dynamic conditions. (c) Temporal change in the intensity of CH2-vss and CH3-vss of SA/HD-d34 measured according to the same rig motion protocol as the film thickness measurements.
