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

2D-IR spectra are tab separated

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

The spectra are sign-inverted (i.e., against the convention of the above manuscript, the bleach is positive, ESA is negative). 
On plotting, the data can simply be multiplied by -1  
The sign of the 2D-IR spectra depends on the order of the phase cycling sequence used or equivalently the processing sequence, and was occasionally 
different on a particular run like this one. 

The ZSM-5 plot in Figure 7 comes from the 0.4 ps perpendicular 2DIR spectrum in the Figure 4 'D-ZSM-5 120C act 1000s av_waiting times_19-05-2021_2DIR' folder
