, 2022 We have investigated the solvent effects on charge-transfer excited states in a donor-acceptor type luminescent material, phenothiazine-triphenyltriazine (PTZ-TRZ), which has characteristic two conformers: quasi-axial and quasi-equatorial conformers ...

New Insights in 4f 12 5d 1 Excited States of Tm 2+ through Excited State Excitation Spectroscopy [PDF]
, 2016 Optical excitation of ions or molecules typically leads to an expansion of the equilibrium bond lengths in the excited electronic state. However, for 4fn−15d1 excited states in lanthanide ions both expansion and contraction relative to the 4fn ground ...

Aromaticity and Antiaromaticity in the Excited States of Porphyrin Nanorings
, 2019 Aromaticity can be a useful concept for predicting the behavior of excited states. Here we show that π-conjugated porphyrin nanorings exhibit size-dependent excited-state global aromaticity and antiaromaticity, for rings containing up to eight porphyrin ...

The calorimetric detection of excited states
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1976 Calorimetric techniques offer the photophysicist and photochemist the opportunity to measure a number of parameters of excited states which may be difficult to obtain by other techniques. The calorimetric strategy seeks to measure the heating of a sample resulting from radiationless decays or chemical reactions of excited states.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Journal of High Energy Physics, 2022 Within the framework of AdS/CFT duality, excited states of the conformal field living at the global AdS boundary of a four-dimensional spacetime Einstein gravity are investigated analytically in the probe limit where the field equations are linearized ...

Some applications of excited-state-excited-state transition densities [PDF]
Physical Review A, 1975 We derive an approximation for transition moments between excited states consistent with the approximations and assumptions normally used to obtain transition moments betwen the ground and excited states in the random-phase approximation and its higher-order approximations. We apply the result to the calculation of the photoionization cross sections of
