Paper Abstract

The effects of finite resolution and different apodisation functions on synthetic Lorentzian bands have been investigated. (The apodisation functions chosen were those commonly available on commercial FTIR spectrometers). The effects are dramatic, the ratio of resolution/(true bandwidth) required to obtain less than 10% distortion (as judged by the peak height and width) in the band varied from 1 for boxcar to less than 0.2 for Norton-Beer (strong). A comparison of calculated and experimental results gave good agreement for the 1216 cm -1cm band of chloroform in deuterochloroform.
