Ultrafast Photodissociation Dynamics of Nitromethane.

Nitromethane (NM), a high explosive (HE) with low sensitivity, is known to undergo photolysis upon ultraviolet (UV) irradiation. The optical transparency, homogeneity, and extensive study of NM make it an ideal system for studying photodissociation mechanisms in conventional HE materials. The photochemical processes involved in the decomposition of NM could be applied to the future design of co...

Time-resolved photoelectron imaging of iodide-nitromethane (I-·CH3NO2) photodissociation dynamics.

Femtosecond time-resolved photoelectron spectroscopy is used to probe the decay channels of iodide-nitromethane (I-·CH3NO2) binary clusters photoexcited at 3.56 eV, near the vertical detachment energy (VDE) of the cluster. The production of I- is observed, and its photoelectron signal exhibits a mono-exponential rise time of 21 ± 1 ps. Previous work has shown that excitation near the VDE of the...

Semiclassical molecular dynamics simulations of ultrafast photodissociation dynamics associated with the Chappuis band of ozone

In this paper we investigate the nonadiabatic ultrafast dynamics of interconversion between the two lower lying excited states of A9 symmetry ~1 A9 and 2 A9) of ozone following photoexcitation of the molecule in the gas phase with visible light. Our algorithm involves a semiclassical initial value representation method which is able to describe electronically nonadiabatic processes within the t...

Ultrafast spectroscopy of oxyhemoglobin during photodissociation.

Ultrafast time-resolved pump-probe spectroscopy was studied to clarify the detailed mechanism in the photodissociation process of oxyhemoglobin in the visible spectral range. The photodissociation had not been time-resolved and only the upper limit of the time needed for the dissociation process was claimed to be faster than 50 fs; it was time-resolved to be 45 +/- 5 fs with 10 fs time resoluti...

Ultrafast reaction dynamics in cluster ions: Simulation of the transient photoelectron spectrum of I2 Arn photodissociation

The photodissociation and recombination of a dihalide ion embedded in a cluster illustrates the crucial role played by the solvent in chemical reactions that involve charged species. In these strongly interacting systems, the solvent does not merely interrupt and redirect motion on the potential energy surfaces of the isolated molecule, it profoundly modifies the surfaces themselves. As the dih...
