ABSTRACT The temperature dependence of the reaction rate coefficients (k) for the reactions of hydroxyl radical with three alkenes was measured by using laser‐induced fluorescence techniques in the temperature range of 298–750 K. The negative temperature dependence of k was observed for each reaction in the low‐pressure range.

TD-DFT Insight into Photodissociation of Co-C Bond in Coenzyme B12
Coenzyme B12 (AdoCbl) is one of the most biologically active forms of vitamin B12, and continues to be a topic of active research interest. The mechanism of Co-C bond cleavage in AdoCbl, and the corresponding enzymatic reactions are however, not well ...

The effects of nitric oxide cooling and the photodissociation of molecular oxygen on the thermosphere/ionosphere system over the Argentine Islands [PDF]
In the past the global, fully coupled, time-dependent mathematical model of the Earth's thermosphere/ionosphere/plasmasphere (CTIP) has been unable to reproduce accurately observed values of the maximum plasma frequency, foF2, at extreme geophysical ...

Photodissociation dynamics of HCOOH(Ã)
The technique of Doppler-resolved, polarised LIF spectroscopy has been employed in a study of the energy and momenta disposal in the OH fragments generated via photodissociation of HCOOH (A 1A″) at 225 nm. The majority of the excess energy resides in fragment translation (≈ 78%) and internal excitation of the HCO fragment (≈ 12%).

Ion Activation Methods for Top‐Down Proteomics
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)
