Quantum Mechanics: An Introduction
EXAMPLE 11.1 The Stark Effect As an example of perturbation theory, we now
calculate the level splitting of a hydrogen atom in a homogeneous electric field.
As we shall see, the effect of the electric field on an atom is to split the spectral
lines ...

Vibrational Spectroscopy: Theory And Applications
5.14 THE STARK EFFECT When the rotational spectrum is recorded in the
presence of a strong electric field, the lines in general will split and are shifted.
This effect was first observed in atomic spectra and is known as the Stark effect.
On the ...

Semiconductor Nanocrystals: From Basic Principles to ...
In addition to state filling, the photoexcitation of carrier populations leads to the
generation of local fields that modify the optical spectra of QDs due to the Stark
effect. The Stark effect leads to a shift of optical transitions and changes in
transition ...

Terahertz Spectroscopy: Principles and Applications
At low intensities, the AC Stark effect dominates, leading to a red shift in the 1s
exciton, but at higher intensities the AC Stark effect saturates, leading to a
blueshift from the DFKE. For frequencies above the 1s → 2p transition, the two
effects act ...

Laser-Induced Breakdown Spectroscopy
The interaction between the atom and this electric field is described by the Stark
effect which splits and shifts the energy levels of the atom. The perturbation to the
energy levels caused by the electric field is proportional to F only in the case of ...
Jagdish P. Singh, Surya Narayan Thakur, 2007
6
Quantum Mechanics in a Nutshell
The Stark effect is the linear splitting of some energy levels in a constant electric
field F in atomic hydrogen. The phrase ''linear splitting'' means that the change in
energy levels occurs to the first power of the electric field: DE!F. This behavior is ...

Ultrafast Spectroscopy of Semiconductors and Semiconductor ...
One of the most interesting phenomena in this regime is that of AC Stark effect on
excitonic states in semiconductors. AC or dynamic Stark effect is well known in
atomic physics and refers to the shift (splitting) of the atomic energy levels ...
8
Rotational Spectroscopy of Diatomic Molecules
An extremely important difference, however, is that in contrast to the nuclear spin
Zeeman effect, the Stark effect in a ' E state is second- order, which means that
the electric field mixes different rotational levels. This aspect is thoroughly ...
John M. Brown, Alan Carrington, 2003

Introduction to Perturbation Theory in Quantum Mechanics
As illustrative examples we consider the Stark and Zeeman effects in hydrogen
and the hydrogen molecular ion in the Born-Oppenheimer approximation [53].
The Schrodinger equation for the Stark effect in hydrogen is separable in
parabolic ...
Francisco M. Fernandez, 2000
The Stark effect is the electric analogue of Zeeman effect. In 1913, Stark
demonstrated that every line in the Balmer series of hydrogen, when excited in a
strong electric field (100000 V/cm), is split into a number of components. When
viewed ...
