Dielectric functions of iso-propanol and di-iso-propylether in the infrared
Abstract
igh-frequency dielectric functions of neat liquid iso-propanol and di-iso-propylether have been investigated and discussed. This included determining the spectra of real and imaginary components of complex electric permittivity and complex polarizability in the NIR–MIR–FIR spectral regions (12,000–200 cm− 1) and also calculation and analysis of molar vibrational polarization for both liquids. The molar vibrational polarization originating from internal vibrational modes has been determined for both molecules for the entire studied spectral region and for various spectral subranges as well. By the use of a recently developed method an attempt was made to ascribe molar vibrational polarization values to particular modes. The vibrational polarization values obtained for di-iso-propylether have been compared with the data determined earlier for di-n-propylether. The obtained results also allowed for an estimation of vibrational polarization due to hydrogen-bond formation in neat liquid iso-propanol. It was found that the vibrational polarization of hydrogen-bonded OH group increases significantly when compared to non-bonded OH group.
