... the S1/2 → D5/2 transition, which has a natural lifetime of about 1,17s. The transitions at 397nm, 866nm and 854nm are used for cooling the ions, repumping them to the electronic ground state and readout techniques. From [14] about 1s. The S1/2 and D5/2 states are used to encode the qubit and it can ...

Early-time dynamics of the photoexcited hydrated electron
... In this paper we report the latest results on the early dynamics of the hydrated electron obtained with an unprecedented time resolution of 5-fs pulses. Based on the comparison of photon echo signals from hydrated electrons and from water alone, we derive a 1.6 fs pure dephasing time of the hydrated ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
