the formation constants (log k), of the complexes formed between a number of amino acids(glycine , l-valine and l-alanine) with p-sulfonatocalix [4] arene at varying temperatures (25± 0.1to 65 ± 0.1 °c) in aqueous solutions and at natural ph of p-sulphonato-calix [4] arene (ph=3.2) bymeans of uv-vis spectrophotometeric technique have been investigated. at this ph the guestmolecule is in its cat...
the interaction between eriochrome black t and li , na , k ,mg and ca ions in acetone and dimethylsulphoxide solutions has been investigated spectrophotometrically. the formation constants of the resulting 1 : 1 complexes were determined and found to decrease in the order mg >ca >li >k >na in both solvents used. there is an inverse relationship between the stabilities of the complexes and the s...
We build a Markov partition of the Feigenbaum dynamical plane, and a system of “external rays”, which are invariant under rescaling. Applications to geometry of the Feigenbaum map are given.
