Heavy Atom- and Deuterium Isotope Effect in Bis-(Phenylethinyl)-Mercury
The influence of mercury as a heavy atom on the spin orbit coupling is investigated in bis(phenylethinyl)-mercury and its deuterated derivative. From the experimental results we draw the following conclusions: a) the symmetry of the molecule is D2 , b) the large spin orbit coupling of the mercury atom is introduced via djr p^-interaction, c) local a jr-transitions and vibronic coupling are of n...
متن کاملInverse Deuterium Isotope Effect in the Intersystem Crossing of Diphenylcarbene
They are important chemical intermediates whose spin state dependent chemistry is implicated in a large number of organic reactions [l-4]. An important feature relevant to an understanding of many of their physical and chemical properties is the small energy gap separating the lowest singlet and triplet states. In fact for a number of carbenes these two states are in equilibrium at room tempera...
متن کاملNovel PEFC Application for Deuterium Isotope Separation
The use of a polymer electrolyte fuel cell (PEFC) with a Nafion membrane for isotopic separation of deuterium (D) was investigated. Mass analysis at the cathode side indicated that D diffused through the membrane and participated in an isotope exchange reaction. The exchange of D with protium (H) in H₂O was facilitated by a Pt catalyst. The anodic data showed that the separation efficiency was ...
متن کاملDeuterium Isotope Effects on the Silver
Solvent deuterium isotope effects support the view that the p-N02 and p-Me derivatives of benzaldehyde S.S-diethylacetal undergo silver ion-promoted hydrolysis in water by different mechanisms. scheme common [3] for O.O-acetals in the presence of H30 + ions, while for the latter we suggested a bimolecular A2-type mechanism with one (or more) water molecules in the slow phase of step (3). The co...
