We collect FTIR measurement on a Bruker Tensor 27 with 1 cm -1 resolution. 2D IR measurements are collected at 2 kHz with ~150 fs pulses, centered at ~2150 cm -1 and magicangle polarization. The 2020 data are collected with 15 μJ pump energy and 200 mM MeSCN in DMSO. The 2021 data are collected with 2 μJ pump energy and 400 mM MeSCN in DMSO. Edge-pixel referencing subtracts correlated local-oscillator noise. The 2020 data are collected with a 4-pulse, real-valued phase cycle while the 2021 data are collected with an 8-pulse, complex-valued phase cycle. Comparative tests have led us to conclude that model fitting works equally well for fitting to real-valued or complex-valued free induction decays, given an equal number of laser shots.
