AFM-IR images and spectra of commercial polymers

This data set contains photothermal IR images (AFM-IR) and spectra of a commercial polymers taken with a Bruker nanoIR3. A Daylight solutions MIRcat-QT external cavity quantum cascade laser. Fourier transform infrared (FTIR) spectra were recorded with Bruker Tensor 35 spectrometer using a "Platinum ATR" (Bruker) attenuated total reflection sampling accessory with a diamond ATR element.

The AFM-IR raw data files (".axz") are gzipped XML files that can be opened with the anasyspythontools python library. FTIR files (".txt") are CSV files. The first column represents wavenumbers, the second column represents absorption.
