Another legacy of the late nineteenth century was identification of the electron by an appropriate interpretation of the Pieter Zeeman effect in 1896, and more especially by J. J. Thomson s experiments the... 

Pieter Zeeman was the first to study the effect of an applied magnetic field on atomic emission spectra. Since a perpendicular applied field was subsequently typically used within Zeeman (excited state emission) spectroscopy the normal Zeeman effect is usually described in terms of parallel (II) and perpendicular (J.) plane polarized bands (Figure 1). It should be noted, however, that Zeeman also studied the parallel magnet alignment used within MCD spectroscopy. In Zeeman s words during his Nobel prize lecture in 1902 describing results obtained for emission from the 5d orbital of Cd to the 5p orbital,. But let us first consider the rays...

Zeeman effect /zay-mahn/ The splitting of atomic spectral lines by an external applied magnetic field. It was first reported by the Dutch physicist Pieter Zeeman (1865-1943) m 1896. 

Pieter Zeeman (1865-1943), Dutch physicist and pro-l sor at the University of Amsterdam. He became interested in the influence of a magnetic field on molecular spectra and discovered a field-induced splitling of the absorption lines in 1896. He shared the Nobel Prize with Hendrik Lorentz for their researches foto the influerK e of magnetism upon raiSation phenomensT in 1902.

Zeeman effect The splitting of atomic spectral lines by a magnetic field. This effect was found by the Dutch physicist Pieter Zeeman (1865-1943) in 1896. Some of the patterns of line splitting that be explained both by classical electron theory and the BOHR THEORY of electrons in atoms. The Zeeman splitting that can be explained in these ways is known as the normal Zeeman effect. There exist more complicated Zeeman splitting patterns that cannot be explained either by classical electron theory or the Bohr theory. This more complicated type of Zeeman effect is known as the anomalous Zeeman effect. It was subsequently realized that the anomalous Zeeman effect occurs because of electron spin and that the normal Zeeman effect occurs only for transitions between singlet states. 

The observation of spectral lines under high resolution revealed that many possessed a fine structure, and this led to the concept of electronic sublevels. These were named s, p, d and f levels, the letters having their origin in the atomic spectra of the alkali metals in which four series of lines were observed, which were known as sharpy principal, diffuse and fundamental. In 1896 some lines had been found to be split in a magnetic field by Pieter Zeeman (1865-1943), and this phenomenon was now explained in terms of electron spin. Each electron was now described in terms of four quantum numbers principal (n), orbital (/), magnetic m) and spin (5). In 1925 Wolfgang Pauli (1900-1958) put forward his exclusion principle, which stated that no two electrons in a given atom could have all four quantum numbers the same. 

Dutch physicist Pieter Zeeman discovers the Zeeman... 

One of the most straightforward and simple types of magnetic spectroscopy is called Zeeman spectroscopy. Its existence was proposed in 1890 by the Dutch physicist Hendrik Lorentz. If atoms were composed of electrical charges, Lorentz said, these charges should be affected by a magnetic field and a change would be noted in the atomic spectrum. In 1896 a student of Lorentz s, Pieter Zeeman, verified this prediction experimentally. For their work, Lorentz and Zeeman shared a 1902 Nobel Prize.
