The HeI lines can be classed into two groups: those of triplets, of which two very close components are often inseparable, and those of singlets. Each group contains 3 series of lines. Here are the wavelengths for the first lines of each series (for the triplets only the wavelength for the strongest double component is given):
Triplets:
Principal series: 10830.3, 3888.6, 3187.7,…
First secondary series: 5875.6, 4471.5, 4026.2,…
Second secondary series: 7065.2, 4713.1, 4120.8, 3867.5,…
Singlets:
Principal series: 5015.7, 3964.7, 3613.6,…
First secondary series: 6678.1,4921.9, 4387.9,4143.8,4009.3
Second secondary series: 7281.3, 5047.7, 4437.5, 4169.0,4024.0
