Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 33100-27-5, C10H20O5. A document type is Article, introducing its new discovery., Safety of 1,4,7,10,13-Pentaoxacyclopentadecane
The Raman CH stretching spectra of 15-crown-5 and 18-crown-6 in water solution are studied in the temperature interval 5-80 deg C.The method of Fourier deconvolution is applied to resolve the overlapped bands in the complex isotropic and anisotropic spectra.The intramolecular coupling constants and the unperturbed CH stretching frequency are calculated for all studied temperatures.The temperature dependencies are discussed in comparison with the temperature dependencies for 12-crown-4 obtained previously.
