A New Approach toward Transition State Spectroscopy

, 2013
Chirped-Pulse millimetre-Wave (CPmmW) rotational spectroscopy provides a new class of information about photolysis transition state(s). Measured intensities in rotational spectra determine species-isomer-vibrational populations, provided that rotational ...

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

Angewandte Chemie International Edition, EarlyView.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.

Electron Photodetachment from Aqueous Anions. III. Dynamics of Geminate Pairs Derived from Photoexcitation of Mono- vs. Poly- atomic Anions

, 2005
Photostimulated electron detachment from aqueous inorganic anions is the simplest example of solvent-mediated electron transfer. Here we contrast the behavior of halide anions with that of small polyatomic anions, such as pseudohalide anions (e.g., HS ...

Synergism and Radicals Dynamics in the Efficient Degradation of Basic Blue 41 via UV/Chlorine Process: Dependence on Processing Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The UV/chlorine process, a promising advanced oxidation process, demonstrates remarkable synergism and radical dynamics for the efficient degradation of Basic Blue 41 (BB41). This study investigates the effects of processing conditions, including solution temperature (25°C–45°C), pollutant dose (10–40 mg/L), chlorine concentration (100–1000 μM)
