Web11 apr. 2024 · The Raman spectrometer was calibrated using a silicon standard at 520 cm −1. A laser beam with an excitation wavelength of 532 nm and a power of 7.4 mW was used. Measurements were performed at three random points for each sample; thus, 12 Raman spectra were taken per material. WebRaman spectra of micrometer-sized grains of calcite, epsomite, quartz, and olivine show no peak shift relative to larger crystals and no peak broadening at least down to 2 micrometers, which bodes well for the Raman analysis of martian soils. Additional information is contained in the original extended abstract.
