Ground and low-lying excited state potential energy surfaces of diiodomethane in four dimensions
Yijue Ding
We report a set of adiabatic potential energy surfaces (PESs) for diiodomethane, including the ground electronic state and all excited states accessible via single-photon absorptio…
Modeling the coincident three-ion momentum imaging of diiodomethane photodissociation on reduced-dimensional potential energy surfaces
Yijue Ding
We present an efficient theoretical model to simulate observables in the time-resolved coincident three-ion Coulomb explosion experiment of diiodomethane. The model employs two deg…
Imaging transient molecular configurations in UV-excited diiodomethane
Anbu Selvam Venkatachalam, Huynh Van Sa Lam, Surjendu Bhattacharyya +6
Femtosecond structural dynamics of diiodomethane () triggered by ultraviolet (UV) photoabsorption at 290 nm and 330 nm are studied using time-resolved coincident…
Ultrafast photodissociation dynamics of dichloromethane on three-dimensional potential energy surfaces and its Coulomb explosion signature
Yijue Ding
We present efficient and reliable molecular dynamics simulations of the photodissociation of dichloromethane followed by Coulomb explosion. These simulations are performed by calcu…
Modeling the time-resolved Coulomb explosion imaging of halomethane photodissociation with \textit{ab initio} potential energy curves
Yijue Ding
We present an effective theoretical model to simulate observables in time-resolved two-fragment Coulomb explosion experiments. The model employs the potential energy curves of the…
Surface hopping molecular dynamics simulation of ultrafast methyl iodide photodissociation mapped by Coulomb explosion imaging
Yijue Ding, Loren Greenman, Daniel Rolles
We present a highly efficient method to directly simulate the photodissociation followed by Coulomb explosion of methyl iodide. In order to achieve statistical reliability, more th…
