Extended Data Fig. 3: Raman spectra collected on Raman spectrometer #1.

From: Absence of near-ambient superconductivity in LuH2±xNy

Extended Data Fig. 3

The black curve (upper one) shows the raw data measured on the LuH2±xNy sample (SR1) using the Raman spectrometer #1, while the orange curve (bottom one) shows the background signal of the instrument without the sample nor the DAC. It is clear that the bands around 106 cm−1, 115 cm−1, 122 cm−1, 129 cm−1 and 138 cm−1 are originated from the instrument itself.
