Hyperfine Structure and Tunneling Motion in Ethylenediamine
The first investigation of the microwave spectrum of ethylenediamine (NH CH –CH NH ) showed that in the gas phase this molecule occurs in two conformers which both exhibit a large amplitude tunneling motion corresponding to an interchange of the roles of the amino groups. In conformer I, the tunneling splitting is about 172 MHz while it is only 2.7 MHz in conformer II. In the paper an analysis ...
متن کاملAllergy to the ethylenediamine component of aminophylline.
Intravenous aminophylline is used as a first line treatment for bronchial asthma. This preparation consists of theophylline or a salt of theophylline dissolved in a solution of ethylenediamine, which confers greater solubility and reduces the alkalinity of the drug.1 In clinical usage side effects of tachycardia, seizures and nausea are well known. We report on the much less common, but clinica...
متن کاملThe Effect of Theophylline with Ethylenediamine
Cheyne-Stokes respiration, found associated with cardiac failure, has been attributed to cerebral anoxia (1) on the basis of decreased cerebral blood flow, which is depressed in proportion to the decrease in cardiac output (2). Since Aminophylline increases cardiac output (3) and at the same time arrests Cheyne-Stokes respiration (4), it seems logical to conclude that the latter response occurs...
متن کاملChemically modified activated carbon with ethylenediamine for
Carbon active chemically bonded ethylenediamine as one sorbents successfully were applied for the enrichment of trace amount of some metal ions. The influences of the variables including pH, amount of solid phase, sample flow rate, type and condition of eluting solution and sample volume on the metal ions recoveries were investigated. The method has high sorption-preconcentration efficiency eve...
