New approaches to vibrational spectroscopy of zeolite catalysts: a perspective

Abstract

This perspective discusses three alternative techniques which complement conventional infrared spectroscopy for obtaining vibrational information about zeolite catalysts and adsorbed molecules: inelastic neutron scattering, infrared micro-spectroscopy, and two-dimensional infrared spectroscopy. The techniques are illustrated briefly and future prospects for their use discussed.

Key words： FTIR; zeolites; INS; micro-spectroscopy; 2D FTIR
