532 nm Raman data on water ice

These are point spectra, presented as xy data in TXT files, of a single point on water ice powder. This data were acquired by Dr. Tuan Vu at Jet Propulsion Laboratory and selected and shared by Dr. Ellen Czaplinski at Jet Propulsion Laboratory in 2023. The instrument used was a Horiba Jobin Yvon LabRam HR spectrometer with a frequency-doubled Nd:YAG laser (532 nm) as the excitation source. Frequency calibration was performed with a Si chip (520.7 cm-1) and spectra were acquired at a 0.5 cm-1/pixel resolution (1800 grooves/mm) with a 50x objective.
