Spectroscopic Evidence of Jet-Cooled p-Chloro-α-Methylbenzyl Radical in Corona Excitation

Abstract

We report the first spectroscopic evidence of the jet-cooled p-chloro-α-methylbenzyl radical. The visible vibronic emission spectrum was recorded from the corona discharge of precursor p-chloro-ethylbenzene seeded in a large amount of inert carrier gas helium using a pinhole-type glass nozzle coupled with a technique of corona excited supersonic expansion. From the comparison with the vibronic spectrum of the p-chlorobenzyl radical, we identified the evidence of formation of the jet-cooled p-chloro-α-methylbenzyl radical in the corona discharge of precursor p-chloro-ethylbenzene.

Process and Study of Hydrotalcites Synthesized by Chemical Coprecipitation at Vacuum, and its Use for Absorption of Agroindustrial Herbicides

“…3, the peaks show atoxic collation in the major peaks [7,8]. Possibly toxic anions formed ainter layer with carboxylic groups bounding to the plates of HT [9][10][11][12]. According to IR analysis shows in the Fig.…”

“…It is observed that the acidic conditions HT, this adsorb more at a pH of 6. So it is assumed that the anionic HT operates in its interlayer [9][10][11][12]. As shown in the Fig.…”
