DATA REPOSITORY - AUTHORS CORRECTION TO NATURE COMMUNICATIONS "PRECISE DETERMINATION OF GRAPHENE FUNCTIONALIZATION BY IN SITU RAMAN SPECTROSCOPY" [P. VECERA, J. C. CHACÓN-TORRES, NATURE COMMUNICATION 8, 15192 (2017)] RAMAN EVOLUTION SPECTRA. This data repository contains experimental Raman spectra of the sp3 defect site formation stages in K-doped graphene exposed to H_2O, O_2 and H_2. The data are presented in Figs.1 and 2 of the authors correction mentioned above. There are three folders: 1. Experimental K-doped graphene (nK^+C_8^{n-}) exposed to water vapour (H_2O) as a function of time upto a fully hydrogenated material exposed to ambient conditions (nK^+C_8^{(n-m)-}H_m). The folder name is "KC8_H2O_Fig1c_MS". This folder contains eleven text files with pairs of datasets in columns: The first column the Raman shift in cm^-1 and the second column the Raman intensity in cts. The files are named by the labels in Figure 1 Authors Correction (ie. "KC8_H2O_00" corresponds to trace (00),"KC8_H2O_01" to trace (01), and so forth"). 2. Experimental K-doped graphene ((KC_8)_n) exposed to hydrogen gas (H_2) as a function of time upto a fully saturated H_2 condition ((H_2)@nK^+C_8 ^{n-}). The folder name is "KC8_H2_Fig2a_SI". This folder contains seven text files with pair of datasets in columns: The first column the Raman shift in cm^-1 and the second column the Raman intensity in cts. The files are named by the labels in Figure 2a Authors Correction (ie. "KC8_H2_00" for trace (00),"KC8_H2_01" for (01), and so forth). 3. Experimental K-doped graphene ((KC_8)_n) exposed to oxygen gas (O_2) as a function of time upto an air exposed ambient condition (nK^+C_8 ^{(n-m)-}). The folder name is "KC8_O2_Fig2a_SI". This folder contains eleven text files with pair of datasets in columns: The first column the Raman shift in cm^-1 and the second column the Raman intensity in cts. The files are named by the labels in Figure 2b Authors Correction (ie. "KC8_O2_00" for trace (00),"KC8_O2_01" for trace (01), and so forth). The Raman measurements were performed in-situ inside a flat quartz tube of ~0.7 mm thickness of borosilicate glass (PGO GmbH) under ultra-high vacuum conditions at ∼4 × 10^{−8} mbar. Each measured spectra was performed with a minute of difference at maximum trying to keep thesame focal distance and spot location while the chemical reaction of K-doped graphene was taking place live in real time with: water, hydrogen or oxygen in a sample boat. The Raman measurements were performed at room temperature using a HORIBA LabRam spectrometer with a 514 nm excitation wavelength and between 300 and 3,000 cm^{−1}. To avoid laser-induced deintercalation and photochemistry, the laser power was kept below 0.5 mW.
