铀空心阴极灯850 ~ 4000 nm红外光谱的傅里叶变换谱线鉴别和波数

Stephen L. Redman, James E. Lawler, Gillian Nave, Lawrence W. Ramsey, Suvrath Mahadevan

摘要:

我们提供了新的测量波数和线识别的10 100 UI和UII近红外(NIR)发射线之间的2500 cm-1和12 000 cm-1(4000 nm至850 nm)使用档案FTS光谱从国家太阳天文台(NSO)。该谱线列表包括在Y、J、H、K和L波段(分别为0.9 μm至1.1 μm、1.2 μm至1.35 μm、1.5 μm至1.65 μm、2.0 μm至2.4 μm和3.0 μm至4.0 μm)的孤立铀谱线,并在近红外光谱范围内提供了比钍多六倍的校准谱线。我们提供的线列表使廉价的市售铀空心阴极灯能够用于现有和未来高分辨率近红外光谱仪的高精度波长校准。

英文摘要:

We provide new measurements of wavenumbers and line identifications of 10 100 UI and UII near-infrared (NIR) emission lines between 2500 cm-1 and 12 000 cm-1 (4000 nm to 850 nm) using archival FTS spectra from the National Solar Observatory (NSO). This line list includes isolated uranium lines in the Y, J, H, K, and L bands (0.9 μm to 1.1 μm, 1.2 μm to 1.35 μm, 1.5 μm to 1.65 μm, 2.0 μm to 2.4 μm, and 3.0 μm to 4.0 μm, respectively), and provides six times as many calibration lines as thorium in the NIR spectral range. The line lists we provide enable inexpensive, commercially-available uranium hollow-cathode lamps to be used for high-precision wavelength calibration of existing and future high-resolution NIR spectrographs.
