The snowflake noise can bring many problems to the video detection, so we propose an efficient method based on video surveillance, which is to solve the detection of snowflake noise. This method is based on the basic features of snowflake noise. We e

The translational energy dependence of several gas-phase SN2 and carbonyl addition−elimination reaction rate constants has been measured in an FT-ICR. The relative energy dependences of the reactions are qualitatively consistent with variations in

The electron affinity of the bis(dimethylphosphino)methyl radical was measured to be 35.3 ± 0.2 kcal/mol, using electron photodetachment spectroscopy in an ion cyclotron resonance spectrometer. Using equilibrium measurements, of bis(dimethylphosphin

Branching between reaction channels in activated systems is often observed to vary with changes in the potential energy surface as Δln(k1/k2) ∝ Δ(Δ − Δ ). RRKM calculations demonstrate that in many, but not all, cases the log−linear relatio

Electron impact on fluorinated acetyl compounds RCOCF3 (R = OH, OSi(CH3)3, OCH3, CF3COCH2, CH3COCH2, CH3, 3,5-(CF3)2C6H3CH2) in an FT-ICR spectrometer yields ionic products of m/z = [M − HF]. These products are proposed to arise via a two-step mech

The gas-phase reaction between enolate anions RCOCH2- and CF3COCl has been studied using FT-ICR. Carbon and oxygen acylation with CF3COCl gives distinct ion products. For the series R = CF3, m-XC6H4 (X = CH3, H, OCH3, F, CF3), H, CH3, (CH3)3C, CH2CH,
