Kinetic dissection of individual steps in the poly(C)-directed oligoguanylate synthesis from guanosine 5'-monophosphate 2-methylimidazolide.
A kinetic study of oligoguanylate synthesis on a polycytidylate template, poly(C), as a function of the concentration of the activated monomer, guanosine 5'-monophosphate 2-methylimidazolide,Expand
Magnesium ion catalyzed P-N bond hydrolysis in imidazolide activated nucleotides. Relevance to template-directed synthesis of polynucleotides
Magnesium, an ion necessary in enzymatic as well as in nonenzymatic template-directed polynucleotide-synthesizing reactions, has been found to catalyze the hydroxide ion attack on the P-N bond ofExpand

Surface chemistry of hydrazine on Pt(111)
Abstract The thermal decomposition of hydrazine, N 2 H 4 , adsorbed on a Pt(111) surface at 60 K has been investigated by temperature programmed desorption (TPD), high resolution electron energy lossExpand
SO2 adsorption on Pt(111): HREELS, XPS and UPS study
Abstract The chemistry of SO 2 on Pt(111) has been studied by X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), temperature programmed desorption (TPD) and highExpand
Magnesium Ion Catalyzed P-N Bond Hydrolysis in Imidazolide-Activated Nucleotides. Relevance to Template-Directed Synthesis of Polynucleotides.
A detailed investigation of the hydrolysis of (Ia) in the pH range 6-12.4 at 37 °C is presented.
Limiting concentrations of activated mononucleotides necessary for poly(C)-directed elongation of oligoguanylates
SummarySelected imidazolide-activated nucleotides have been subjected to hydrolysis under conditions similar to those that favor their template-directed oligomerization. Rate constants of hydrolysisExpand
Surface chemistry of 1,1‐dimethylhydrazine on platinum
The surface chemistry of 1,1‐dimethylhydrazine on polycrystalline Pt has been investigated to determine the major reaction pathways followed by this asymmetric molecule. Thermal dissociation plays anExpand
Interaction of low-energy electrons and UV photons with adsorbed CF3Cl on Pt(111)
Abstract The interaction of low energy electrons and UV photons with CF 3 Cl adsorbed on Pt(111) has been studied using temperature-programmed desorption (TPD), photoelectron spectroscopy (XPS, UPS)Expand
Surface-aligned photoreaction of hydrobromic acid-d with ethene on platinum(111)
For ethylene and deuterium bromide coadsorbed on Pt(111) at 52 Y, evidence is presented for photon-driven production of ethane and bromoethane. The formation of bromoethane is ascribed to aExpand
