Stark effect spectroscopy of tryptophan

Stark effect spectroscopy of tryptophan.

The change in permanent dipole moment (magnitude of delta mu) for the transition from the 1La state to the ground state of tryptophan is the key photophysical parameter for the interpretation of tryptophan fluorescence spectra in terms of static and dynamic dielectric properties of the surrounding medium. We report measurement of this parameter by means of electric field effect (Stark) spectros...

Active Stark Atomic Spectroscopy

Active Stark Atomic Spectroscopy (ASAS) method can be used to determine the electric field in the diode of an ion or electron accelerator as a function of position and time, including the positions of anode and cathode plasma emission surfaces (in order to obtain the effective accelerating gap). As possible probe beams, we suggest the use of lithium and sodium atoms. The diagnostic provides a m...

Stark Effect

An electric field partly lifts the degeneracies of atomic energy levels. This splitting was observed by Stark [1] and explained by Schrödinger [2]. We compute the Stark effect on atomic hydrogen using perturbation theory by diagonalizing the perturbation term in the N-fold degenerate multiplet of states with principal quantum number N . We exploit the symmetries of this problem to simplify the ...

Stark spectroscopy of mixed-valence systems.

Many mixed-valence systems involve two or more states with different electric dipole moments whose magnitudes depend upon the charge transfer distance and the degree of delocalization; these systems can be interconverted by excitation of an intervalence charge transfer transition. Stark spectroscopy involves the interaction between the change in dipole moment of a transition and an electric fie...
