In addition, the ethylene system also yields CH4+ C2H+3, nominally a hydride abstraction, but also proceeding through a long鈥恖ived collision complex. Isotopic scrambling in the CD+3+C2H4also confirms the presence of a transient collision complex in the reaction. The similarities accompanying the...

theoretical study of the cf 2 dch 2 f hf + cftch reaction The fluorinated hydrocarbon compounds are efficient agents for depleting stratospheric ozone, and due to this property these compounds have been the subject of extensive experimental studies. Burgess et al.1 reported a fundamental study ....
A method of forming nitrogen-doped or other Group V-doped single-walled nanotubes including: forming a catalyst metal layer on a substrate; loading a substrate having the catalyst metal layer into a reaction chamber; forming an H2O or other plasma atmosp
Later, the Teflon vial containing the reaction mixture was packed in a stainless steel autoclave. Up to this step, this entire procedure was carried out in a moisture-free argon-charged glove box under an inert atmosphere. The autoclave was removed from the glove box and placed in a pre...
