Structures of the molecular wires used in this study are shown in "structures.bmp" Data in the .zip archive is organised in three folders. -\Scanmaster3000\ Contains the software to analyse STM data. Copies of the python script can be also found at https://github.com/dougszumski/Scanmaster-3000-Analysis Copies of the data acquisition software at https://github.com/dougszumski/Scanmaster-3000 -\NMRs\ Contains raw NMRs in Bruker format. The FID can be opened with any software able to handle it. A free software is Spinworks, available at the address: https://home.cc.umanitoba.ca/~wolowiec/spinworks/ [retrieved 26/11/2018]. -\Single-Molecule Conductance\ Contains raw STM data, compressed as tarballs (.tar.gz). Experimental conditions available in the name of the tarball. These can be directly analysed with the python routine Scanmaster3000 (included). Run "chopper.py" first, to cut the tarball into individual STM scans, and then run "sm3000.py" to analyse data an output it as desired. DO NOT EXTRACT THE TARBALL as the chopper will not work on the .txt file. If necessary, ASCII tables can be generated, and these can be further analysed statistically with the attached Origin project "NewOriginTemplate.opj". All python script require python 2.7 and a series of packages, all found in the Enthought Canopy distribution available at https://store.enthought.com/downloads/.
