The compounds all have structures (MeO)3P-Au-(CC)n-Au-P(OMe)3 Folder/compound numbering refer to the number of carbon atoms between the two Au(I) centres. Refer to structures.png for graphical description. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ All zip files are split in smaller volumes (~2GB) to ensure compatibility with 32-bit systems and the University of Liverpool Data Catalogue requirements. There are 3 datasets in this entry. - STMBJ: Regular scanning tunnelling microscope break-junction measurements. Data stored as 3-column, tab-separated ASCII: tip-substrate separation (nm) // bias (V) // Log(G / G0) - IV: Current-voltage characteristics measurements. Data stored as 3-column, tab-separated ASCII: tip-substrate separation (nm) // bias (V) // Log(G / G0) - RAMAN: Raman Spectroscopy on either powder substrates or SERS. Data is stored in proprietary WDF file and 2-column, tab-separated ASCII: Wavenumber (cm-1) // Intensity STMBJ and IV data are raw and should be processed before use (see below). Metadata (experimental conditions such as acquisition speed, method, etc.) is embedded in the filename. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We included custom software to process STMBJ and IV data in a separate archive (Processing VIs). These VIs require LabVIEW 2024 or later to be run. Executables can be compiled using the LabVIEW runtime engine (available free of charge from National Instruments), or are available from the authors upon request. - "LEVIATHAN3_STMBJ Ultimate Data Cruncher_1.1a" can be used to process STMBJ data, to perform trimming of the dataset to enhance processing speed, alignment of electrode separation to rupture of the quantum point contact, and dataset cleanup. - "LEVIATHAN3_IV Data Cruncher_0.99a" can be used to process IV data, to isolate the current-voltage characteristics from the entire experiment and perform the conversion from conductance (Log(G / G0)) to current (nA). Instructions on how to run the VIs are included in a panel in the VIs themselves. Updated version of these software will also be available from the authors upon request. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Feel free to contact skeja@liverpool.ac.uk or sgjmorr8@liverpool.ac.uk for any request regarding this dataset. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Data is released under a CC BY-NC-SA (Creative Commons Attribution-Non Commercial-Share Alike).
