In a Article，once mentioned of 33100-27-5, Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane
The Raman CH stretching spectra of 12-crown-4, 15-crown-5 and 16-crown-6 and their compexes with some metal cations- Li1+, Na1+, J1+ and Cu2+ in water solutions are studied.For the first time Fourier deconvolution is applied to resolve the overlapped components in the corresponding isotropic and anisotropic spectra.A model is introduced which explains the variety of components in the spectra by means of splitting of the unperturbed CH stretching frequency owing to intramolecular interactions and Fermi resonance.The coupling constants of these interactions, as well as all parameters according to the model are calculated for studied crowns and their complexes.The differences in the number and intensity of the resolved components in the spectra of the various crowns are explained with the corresponding differences in the coupling constats and model parameters.It is established that complexation leads to some increase in the unperturbed stretching frequency, probably owing to the increase in strain of the crown molecule.It is concluded that 15-crown-5 forms 2:1 and 1:1 complexes with K+ and Na+ cations respectively and 12-crown-4 forms a 2:1 complex with the Na+ cation.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane, you can also check out more blogs about33100-27-5
