nano-FTIR data is provided as interferogram files ending in "Interferograms.txt.txt" within the individual folders containing the string "NF S". Row: not used Column: not used Run: number of interferogram acquisition Depth: pixel number within one interferogram M: not used O0A: amplitude in V of the 0th demodulation order O0P: phase in radians of the 0th demodulation order O1A: amplitude in V of the 1st demodulation order O1P: phase in radians of the 1st demodulation order O2A: amplitude in V of the 2nd demodulation order O2P: phase in radians of the 2nd demodulation order O3A: amplitude in V of the 3rd demodulation order O3P: phase in radians of the 3rd demodulation order O4A: amplitude in V of the 4th demodulation order O4P: phase in radians of the 4th demodulation order O5A: amplitude in V of the 5th demodulation order O5P: phase in radians of the 5th demodulation order

This is the nano-FTIR data set as shown in Figs 3 and 5 of our publication "Experimental verification of field-enhanced molecular vibrational scattering at single infrared antennas" by D. Virmani et al. This data set was acquired with a NeaSNOM microscopy (attocube AG) and can be opened with Gwyddion (https://gwyddion.net/). Please see the files "notes.txt" within the zip file provided for an identification of the individual data sets.

Additionally, s-SNOM images for finding the antennas prior to nano-FTIR spectroscopy can be found in the folders containing the string "WL"
