Molecular dynamics simulations of D2O ice photodesorption.

Molecular dynamics (MD) calculations have been performed to study the ultraviolet (UV) photodissociation of D(2)O in an amorphous D(2)O ice surface at 10, 20, 60, and 90 K, in order to investigate the influence of isotope effects on the photodesorption processes. As for H(2)O, the main processes after UV photodissociation are trapping and desorption of either fragments or D(2)O molecules. Trapp...

Molecular dynamics of liquid benzene via femtosecond pulses laser excitation

2014 We analyse the complex response of liquid benzene to the applied 45 fs FHWM optical pulses by using a polarization sensitive transient grating technique. An electronic contribution to the nonlinear polarization is distinguished from three other processes which, we demonstrate, originate in polarizability modifications associated to molecular motions. Additionally, we present evidence that ...

Probing molecular dynamics at attosecond resolution with femtosecond laser pulses.

The kinetic energy distribution of D+ ions resulting from the interaction of a femtosecond laser pulse with D2 molecules is calculated based on the rescattering model. From analyzing the molecular dynamics, it is shown that the recollision time between the ionized electron and the D+2 ion can be read from the D+ kinetic energy peaks to attosecond accuracy. We further suggest that a more precise...
