The role of tachysterol in vitamin D photosynthesis - A non-adiabatic molecular dynamics study [PDF]
Physical Chemistry Chemical Physics 19 (8), 5763-5777 (2017), 2017 To investigate the role of tachysterol in the photophysical/chemical regulation of vitamin D photosynthesis, we studied its electronic absorption properties and excited state dynamics using time-dependent density functional theory (TDDFT), coupled cluster theory (CC2), and non-adiabatic molecular dynamics.
