Electric fields split spectral lines: Stark's detailed experimental account

Stark reported that an electric field separates selected gas spectral lines into polarized components, with a detailed 1914 experimental account following his 1913 announcement.

What is recorded here?

Stark reported that an electric field separates selected gas spectral lines into polarized components, with a detailed 1914 experimental account following his 1913 announcement. Atoms reveal information through the light they emit. This experiment showed that an electric field can change a spectral line into several components. Stark compared spectra with and without the field and observed the light across the field direction, reducing a competing shift caused by moving emitters. Hydrogen and helium showed different patterns, creating a new experimental constraint for atomic theory. The detailed paper acknowledged Kirschbaum's essential assistance during long exposures. Measurements were provisional: field estimates, faint components and instrumental resolution limited what could be concluded. It did not supply the later quantum explanation. Stark's 1913 announcement and this 1914 account are linked publications of the same investigation. Antonino Lo Surdo independently observed the phenomenon in 1913; that attribution is supported here by a primary history-of-physics research abstract, while his original experimental body remains unread. This record does not award exclusive discovery ownership.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

The contribution is the reported splitting of specified spectral lines in an applied electric field, with historical instrumental and interpretation limits. It is not a complete quantum derivation or a universal linear splitting law for every atom/field regime. Parallel and later theoretical/experimental work remain separate.
