532 nm Raman spectra of Tissint meteorite
收藏资源简介:
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.
本数据集包含提森特陨石(Tissint meteorite)未抛光样品上10个测点的点光谱数据,相关数据以TXT格式的xy数据文件存储。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)完成分析测试。测试所用仪器为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。频率校准采用硅片(Si chip,520.7 cm⁻¹)完成,光谱采集分辨率为0.5 cm⁻¹/像素,光栅刻线密度为1800条/毫米,所有测试均在室温实验室环境中进行。
