act = actual temperature +/- ~15 C (estimated as described in J.Chem. Phys. 158, 114201 (2023))

Samples prepared and 2D-IR data acquired as described in "Distinctive signatures and ultrafast dynamics of Bronsted sites, silanol nests and adsorbed water in zeolites revealed by 2D-IR spectroscopy", 
Donaldson et al, Chemical Science 2025

The FT-IR spectra are the 'raw' data prior to baselining

2D-IR spectra are tab separated

The pump axis is row 1
The probe axis of parallel and perpendicular detectors respectively are column 1

From the lack of negative time anti-diagonal features at -0.1 ps, the waiting time-zero is likely to be around -0.1 ps
