    GC-FTIR-MS analysis of volatile products in the radiolysis of nitrobenzene-carbon tetrachloride solution (1993)

    Notes: Summary A number of volatile products formed in the gamma-radiolysis of nitrobenzene-carbon tetrachloride solution have been identified using a GC-FTIR-MS technique. The conditions for separation of the products have been described. HCl, COCl2, chlorobenzene, chloro- and dichloronitrobenzene, isomeric di-, tri- and tetrachlorobenzene, hexachloroethane, tetrachloroethylene, α,α,α-trichloromethylbenzene, chloro- and dichloroisocyanatobenzene, and other chloroderivatives are among the important products formed.Ipso-substitution of the nitro group as well as hydrogen atom by chlorine atom and CCl3 free radical is noticed. It is proposed that chloroisocyanatobenzene is formed as the result of interaction of dichlorocarbene and nitrobenzene.

    Alterations in brain norepinephrine metabolism induced by environmental stimuli previously paired with inescapable shock (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-05
    Description: Footshock stress produced an immediate increase in brain concentrations of 3-methoxy-4-hydroxyphenylglycol sulfate (MHPG-SO4), a major metabolite of the neurotransmitter norepinephrine, in the rat brain. Twenty-four hours after footshock stress, when concentrations had returned to baseline, increases in MHPG-SO4 and emotional behavior could be elicited by previously neutral environmental stimuli that had been paired with the stress.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cassens, G -- Roffman, M -- Kuruc, A -- Orsulak, P J -- Schildkraut, J J -- New York, N.Y. -- Science. 1980 Sep 5;209(4461):1138-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403874" target="_blank"〉PubMed〈/a〉
