摘要：

The errors produced by wedging in IR spectra are calculated from theory and also shown experimentally. The effect of these errors is magnified in absorbance subtract spectrometry, is particularly serious at the very high sensitivities FT-IR makes possible. The concentration errors and residual spectra produced by various types of absorbance subtract procedures are shown mathematically and graphically. For known wedging, a correction procedure is shown. If the wedging cannot be measured directly, It can be obtained spectrally from the appearance of known sample bands. © 1979, American Chemical Society. All rights reserved.
