Subject index solid-state

It is impossible to discuss all papers which have appeared on the subjects included in this review (in order to keep it within reasonable limits) most of the important papers are included, and this review should give the reader an insight in the state of the art of solid state infra-red spectroscopy. The attention of the reader is drawn to the existence of Science Citation Index if a reference of this paper is used as a leading reference, Science Citation Index will quickly yield a list of other works which have cited the particular reference, enabling him to do a relatively complete literature search in a short time. 

To acquire better structural information, one has to resort to more advanced solid-state NMR techniques. Here, they will be reviewed by subject rather than in chronological order. First, we shall briefly look at P relaxation. Second, components of the H—> P CP signal will be discussed. Third, much attention will be given to HPO detection by differential H—> P cross-polarization (DCP). Then the P sideband pattern index and chemical shift anisotropy in the study of bone calcification will be briefly reviewed. Finally, a special ADRF-CP technique will be mentioned.

It is not surprising that the data produced as total petroleum hydrocarbons (EPA 418.1) suffer from several shortcomings as an index of potential ground-water contamination or health risk. In fact, it does not actually measure the total petroleum hydrocarbons in the sample but rather, measures a specific range of hydrocarbon compounds. This is caused by limitations of the extraction process (solvents used and the concentration steps) and the reference standards used for instrumental analysis. The method specifically states that it does not accurately measure the lighter fractions of gasoline [benzene-toluene-ethylbenzene-xylenes fraction (BTEX)], which should include the benzene-toluene-ethylbenzene-xylenes fraction. Further, the method was originally a method for water samples that has been modified for solids, and it is subject to bias.
