Paper Abstract

The specificity and sensitivity of infrared spectroscopy for the characterisation of organic compounds have long been recognised, and with continuing improvements in instrumental performance and in sampling procedures it is now possible to obtain good quality spectra from rangecebiological materials and from coals, both of which were previously regarded asrather intractable. The structural complexity of these materials, and of some synthetic polymers, leads to the occurrence of strongly overlapped peaks, whose half widths are usually appreciably greater than the instrumental resolution employed, thus preventing their separation. Furthermore, these three types of material, being of high molecular weight, are not readily soluble, must be examined in the condensed phase, where intermolecular interaction adds to the band broadening and the consequential overlap. This overlap reduces the value of the spectra for structural diagnosis and quantitative measurements.
