Shock-to-detonation transition of nitromethane: Time-resolved emission spectroscopy measurements

Application of Detonation Shock Dynamics to the Propagai’ion of a Detonation in Nitromethane in a Packed Inert Particle Bed

A multidimensional implementation of DSD, formulated with the level set method, is applied to track the propagation of a detonation wave in a heterogeneous explosive consisting of an array of inert cylindrical obstacles with a liquid explosive in the interstitial space. With the Huygens assumption, the average detonation velocity through the explosive is less than that for the liquid explosive ...

Time-resolved scanning tunneling microscope light emission spectroscopy of Sb2Te3

We have successfully added ps temporal resolution to scanning tunneling microscope (STM) light emission spectroscopy. STM light emission spectra of Sb2Te3 were measured in the configuration that the tip sample gap of the STM is irradiated by a pair of pump and probe laser pulses with a duration less than 2 ps each, and were analyzed as a function of optical delay time between the pump and probe...

Introduction to time-resolved spectroscopy

Time-resolved wavelength modulation spectroscopy measurements of HO 2 kinetics.

High-frequency wavelength modulation spectroscopy (WMS) has been applied to the detection of the hydroperoxyl radical (HO2 ) in a laser photolysis and long-path absorption pump-probe kinetics reactor with a near-infrared distributed feedback diode laser. The HO2 is formed by the 355-nm photolysis of Cl2 in the presence of CH3 OH and O2 and monitored by a phase-sensitive detection of the second-...
