متن کاملBromine-79 NQR for uncoordinated Br ions in fraw5-[CoBr2(en)2][H502]Br2*
A single 7 Br N Q R line showing a frequency of 19.594 M H z at room temperature has been observed in the crystals of trans-[CoBr2(en)2] [ H 5 0 2 ] B r 2 and assigned to the B r " ions which are not coordinated to the central Co(II I) atom. The electric field gradient (EFG) at the B r " nuclei arises from O H • • • B r " hydrogen bond formation between the B r " ions and the terminal O H hydro...
متن کاملBromine Toxicological Overview
The major route of exposure is by inhalation. Acute inhalation exposure to bromine vapour may cause upper respiratory effects, cough, headache, CNS effects and lacrimation. Acute oral exposure to bromine results in central nervous system effects. Deep partial skin loss and skin discolouration have been reported following acute dermal exposure to bromine. Ocular exposure to bromine cau...
متن کاملThe chemistry of atmospheric bromine
Bromine may act as a catalyst for recombination of ozone and could be more efficient than either nitric oxide or chlorine. The lower atmosphere contains small concentrations of gaseous bromine produced in part by marine activity, in part by volatilization of particulate material released during the combustion of leaded gasoline, with an additional contribution due to the use of methyl bromide a...
