Abstract

FTIR spectra of deuterated acetonitrile (ACD) adsorbed on Co-Beta zeolite were investigated. By analysing the IR region of zeolite framework perturbation, the conditions for the prevailing presence of the Co-ACD complex with 1 : 1 stochiometry were established. Analysis of the C≡N region with overlapping bands OH···ACD (2 297 cm<sup>-1</sup>), and Lewis(Al)···ACD (2&nbsp;325&nbsp;cm<sup>-1</sup>), provided a value of molar absorption coefficient for a band of Co-ACD complex in Co-Beta at 2 310 cm<sup>-1</sup> equal to 7.12 ± 0.3 cm μmol<sup>-1</sup>. <p>
