532 nm Raman spectra of Tissint meteorite

These are point spectra, presented as xy data in TXT files, of ten points of an unpolished piece from Tissint meteorite. This piece was lent by Dr. Andrew Steele and analyzed by Dr. Sunanda Sharma in 2024. 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) in an ambient temperature laboratory environment.本数据集收录提辛特陨石（Tissint meteorite）一块未抛光样品上10个检测点位的点光谱数据，光谱以TXT文件内的xy数据格式存储。该样品由安德鲁·斯蒂尔博士（Andrew Steele）借出，并于2024年由孙达·夏尔马博士（Sunanda Sharma）完成检测分析。所用仪器为Horiba Jobin Yvon LabRam HR型光谱仪，以倍频Nd:YAG激光器（532 nm）作为激发光源。实验以硅片（520.7 cm⁻¹）完成频率校准，光谱采集分辨率为0.5 cm⁻¹/像素，光栅刻线密度为1800条/mm，测试环境为室温实验室条件。
