Theory of infrared absorption spectrometry
Webb2 INFRARED SPECTROSCOPY mind is that a successful interpretation is based not only on the presence of particular bands within the spectrum, but also the absence of other important bands. Complete classes of compounds can be rapidly excluded during the interpretation by the use of no-band information. It must be understood that this article … WebbWe have constructed an infrared electroabsorption spectroscopic system employing the alternating current (AC) coupled dispersive method developed previously in our …
