چکیده
The electron stimulated desorption of D anions from deuterated hydrocarbons condensed on a platinum substrate has been studied experimentally. D anion yield functions are reported for incident electron energies ranging from 0 to 20 eV: For each molecule studied, the yield function exhibits a single dissociative attachment resonance at approximately 10 eV: Above 15 eV; a linearly increasing D ion signal due to dipolar dissociation was recorded. No heavier polyatomic anion fragments were observed to desorb. r 2003 Elsevier Science Ltd. All rights reserved.

2H Isotope Effect on 13C Chemical Shifts of Nitro-Benzo-9-Crown-3
Deuterium substitution on two ortho-substituted-OCH2-fragments in Nitro-Benzo-9-Crown-3 induces low frequency shifts, positive mnDCj, in all 13C NMR resonances which is an indication of the increased shielding in this crown ether. The magnitude of these shifts vary from 15DC7=716 to 54D<...
متن کاملEvaluation of various factors relating to intraocular pressure and C/D ratio
Introduction: Intraocular pressure (IOP) is determined by three factors: the rate of aqueous humor production by the ciliary’s body, the resistances to aqueous out flow across the trabecular meshwork and the level of episcleral vessel pressure. IOP varies with a number of factors, including: age, sex, race, systemic disease and diurnal variation. The purpose of this study is measurement of IO...

متن کاملThe Citrullus Colocynthis pulp antioxidant activity on oxidative stress factors of liver in streptozotocin-induced diabetic rats
Introduction: Diabetes mellitus is a metabolic disorder and it is estimated that its annual incidence rate will continue to increase in the future worldwide. Increased oxidant factors and decreased antioxidant defense are two of the factors resulting in diabetes. In the present study, we aimed to investigate Citrullus Colocynthis pulp effects on oxidant and antioxidant factors of liver in st...

In the combination of 5-fluorophenyl-1, 3, 7, 9-tetra methylpyrido [2, 3, d, d, 5, 6 dipyrimidine -2, 4, 6, and 8 tetron, there are 4 rings, respectively, ring that is attached to the halogen ring A and, respectively, a ring The lower and the right to the left of the ring A are called C, B, and D. Calculations and studies show that the amount of aromatics in halogen-ring A in all cases has the ...
