WAVELENGTHS OF SPECTRAL LINES IN MERCURY PENCIL LAMPS

摘要

The wavelengths of 19 spectral lines in the region 253-579 nm emitted by Hg pencil-type lamps were measured by Fourier-transform spectroscopy. Precise calibration of the spectra was obtained with wavelengths of Hg-198 as external standards. Our recommended values should be useful as wavelength-calibration standards for moderate-resolution spectrometers at an uncertainty level of 0.0001 nm. [References: 6]
