Cluster Photofragmentation Dynamics: Quasiclassical Trajectory Studies of Ar n -H 2 S and Ar n -SH (n=1,2)

December 1, 2000

Author(s)

J R. Fair, David Nesbitt

Quasiclassical trajectory calculations with model potential energy surfaces have been used to elucidate the formation dynamics of open-shell radical clusters by gentle-recoil photolysis of closed-shell hydride clusters. Specifically, model surfaces for Ar

Quantum State-Resolved Scattering of F + CH 4 -> HF(v,J) + CH 3 ; Nascent HF(v,J) Product State Distributions

September 1, 2000

Author(s)

W W. Harper, S A. Nizkorodov, David Nesbitt

State-to-state reactive scattering of F+CH 4->HF(Ņ,J)+CH 3 is studied usihng crossed supersonic jets and high-resolution (δŅnearly equal to}0.0001 cm -1) IR laser direct absorption techniques. Rovibrational state-resolved HF column-integrated absorption

Bond-Breaking in Quantum State Selected Clusters: Inelastic and Nonadiabatic Intracluser Collision Dynamics in Ar-H 2 O -> Ar + ( 2 S)+ OH( 2 P 1/2, 3/2;N)

May 1, 2000

Author(s)

O Votava, David F. Plusquellic, T L. Myers, David Nesbitt

High resolution vibrationally mediated IR + UV photodissociation methods are used to investigate the dvnamics of H-OH bond breaking in quantum state selected H 2O and Ar-H 2O van der Waal complexes prepared in a slit supersonic jet expansion. This

Temperature Dependent Kinetics of the OH/HO 2 /O 3 Chain Reaction by Time-Resolved IR Laser Absorption Spectroscopy

May 1, 2000

Author(s)

S A. Nizkorodov, W W. Harper, B W. Blackmon, David Nesbitt

This paper presents an extensive temperature dependent kinetic study of the catalytic HO x ozone cycle, (1) OH + O 3 -> O 2 and (2) HO 2 + O 3 -> OH + O 2, based on time-resolved, Doppler limited direct absorption spectroscopy of OH with a single mode (δŅ

Nonexponential Blinking Kinetics of Single CdSe Quantum Dots: A Universal Power Law Behavior

February 1, 2000

Author(s)

M Kuno, D P. Fromm, H F. Hamann, Alan Gallagher, David Nesbitt

We have studied the fluorescence intermittency of single CdSe quantum dots (17-29 radius) overcoated with ZnS. Optical measurements were made using a confocal microscope under epillumination conditions, with the 488 nm line of an Ar + laser as the
