“Recent Advances in Multidimensional Ultrafast Spectroscopy”
By Thomas A. A. Oliver

There are a total of twenty three files in the data set.

Real valued isotropic 2DIR spectra for Methylammonium lead iodide perovskite thin film samples were recorded for many different waiting times (t2). The subfolder labelled 2DIR data contains multiple 2DIR data surfaces in individual csv files, labelled with the corresponding t2 waiting time. Rows correspond to the pump, omega1 axes, and columns to omega3. Omega1 and omega3 axes are provided as separate csv files.
