Spectroscopy of the I - I H I Transition - State Region by Photodetachment of IHI - A
نویسنده
چکیده
The transition-state region of the I + HI reaction has been studied by photoelectron spectroscopy of IHIand IDI-. A well-resolved progression in the asymmetric stretch of the neutral IHI (IDI) complex is observed in each spectrum. These peaks apparently correspond to states of the complex that are unstable with respect to dissociation into I + HI (DI). The experimental peak positions, widths, and intensities are compared to simulated spectra generated from a collinear model potential energy surface. The results provide strong experimental evidence for quasi-bound states in heavy + light-heavy reactions.

Threshold Photodetachment Spectroscopy of the I + H I Transition - State Region
High-resolution threshold photodetachment spectroscopy of IHIshows transitions to metastable symmetric stretch levels of the [IHI] complex which were not resolved in earlier work. The observed transitions are as narrow as 30 cm-I, providing definitive evidence for the existence of relatively long-lived states of the [IHI] complex. These metastable states are responsible for the reactive resonan...
متن کاملAnion Photoelectron Spectroscopy of Solvated Transition State Precursors
Photoelectron ~PE! spectra have been collected for the clustered bihalide anions XHX•~M! ~X5Br, I! and BrHI•~M!, where M5H2O, HBr, and HI, in order to probe the effects of strongly solvating species on the PE spectra of transition state precursor anions. The PE spectra of the XHX•~H2O) ions show similar vibrational progressions as the spectra of the bare BrHBr and IHI anions, indicating that ph...

In this paper, we have focused on the preparation and characterization of copper oxide nanoparticles by solid state thermal decomposition of copper(I) iodide in the presence of thiosemicarbazone ligands without the need for a catalyst, employing toxic solvent, template or surfactant and complicated equipment, which makes it efficient, one-step, simple and environment-friendly. CuO nanoparticles...
متن کاملP-64: The Relationship between Polymorphism in Gene of Insulin-Like Growth Factor-I and The Serum Periparturient Concentration in Holstein Dairy Cows
Background: One of the most important metabolic factors affecting the reproductive activity is insulin-like growth factor-I (IGFI) concentration changes after calving. Recently, Maj et al. (2008) discovered a significant association between the IGF-I genotypes based on the 5'-untranslatedregion (5'-UTR) of IGF-I gene and the IGF-I blood level. The objective of this study is to investi...
