16 Μαρ 2023 · The excited state has one electron in the \(\pi\)-orbital and one electron in the \(\pi\) *-orbital as shown in Figure \(\PageIndex{1}\). In this case, there are two possible ways we might align the spins.
25 Αυγ 2021 · Among many chemical processes induced with photon absorption, the excited-state intramolecular proton transfer (ESIPT) stands out with its ultrashort timescale and strong impact on the molecular electronic structure, which is often manifested with large emission Stokes shifts.
UV spectroscopy is also very useful in the study of proteins. Proteins absorb light in the UV range due to the presence of the aromatic amino acids tryptophan, phenylalanine, and tyrosine, all of which are chromophores.
19 Νοε 2020 · Excited states can be computed in a single-reference approach by equation-of-motion-CC (EOM-CC), where the excited-state wave function is written as an excitation operator times the ground-state wave function.
20 Μαΐ 2021 · Machine learning (ML) can be used to predict properties associated with the excited states of a molecule fast after learning on quantum mechanical (QM) or experimental data. ML models can also...
3 Ιουλ 2018 · Organic fluorophores with intramolecular hydrogen bonds (H-bonds) are powerful model compounds in the study of proton-transfer reactions 1, which are among the most fundamental and...
