Catal. 2002, 142, 1877–1884doi: https://doi.org/10.1016/S0167-2991(02)80364-0Abstract:In this paper, the vibrational spectra of the natural zeolite bikitaite obtained from ab initio MD simulations are discussed. The calculated spectra, in line with experimental IR and Raman spectra of other zeolitic systems, predict that
