Evolution has ensured that plants and animals have developed effective protection
mechanisms against the potentially harmful effects of incident ultraviolet radiation (UVR) …

In an effort to illuminate why nature has chosen a particular set of bio-molecular 'building-
blocks' for life, recent years have seen an up-surge of gas-phase spectroscopy experiments …

Conical intersection as a dynamic funnel in nonadiabatic transition dictates many important
chemical reaction outputs such as reaction rates, yields, and energy disposals especially for …

Oxybenzone (OB) and ferulic acid (FA) both find use in commercial sunscreens; caffeic acid
(CA) differs from FA by virtue of an− OH group in place of a− OCH3 group on the aromatic …

The non-equilibrium thermo-field dynamics formulation of the hierarchical equations of
motion combined with the tensor-train representation of the density matrix is discussed, and …

Eumelanin (EM) and pheomelanin (PM) are ubiquitous in mammalian skin and hair–
protecting against harmful radiation from the sun. Their primary roles are to absorb solar …

Ultraviolet spectroscopy of the G-and S-type lignin subunits, guaiacol (G) and syringol (S),
along with their para-methylated derivatives 4-methylguaiacol (4-MG) and 4-methylsyringol …

The catechol functional group plays a major role in the chemistry of a wide variety of
molecules important in biology and technology. In eumelanin, intermolecular hydrogen …

Using a combination of ultrafast solution-and gas-phase spectroscopies, together with high-
level theory calculations, we demonstrate that we are able to track conformer-specific …

The electronic spectra of cold protonated aromatic amines: anilineH+ C6H5–NH3+,
benzylamineH+ C6H5–CH2–NH3+ and phenylethylamineH+ C6H5–(CH2) 2–NH3+ have …
