Visible lines



The following are the lines in the visible (including near IR and near uv) portion of the spectrum. Note that all numbers refer to air wavelengths, not vacuum wavelengths. Only lines from the neutral atom are listed. With only a few exceptions you are not likely to see lines from the ion spectrum. Note also the lines below about 300 nm are absorbed by glass.
Wavelengths are given in Ansgtroms. To convert to nanometers divide by 10. For example, in the helium spectrum the listed wavelelngth 4471.479 Angstroms is also equal to 447.1479 nm.
