Peak height intensity

Phase identification was done on the basis of both d-spacing and the peak height intensity of all the x-ray lines. These values were compared with values obtained for the end-member (unsubstituted) compounds and also calculated by means of the Lazy-Pulverix computer program (9). Precision lattice parameters were obtained by the Debye-Scherrer method with a 114.6 mm dia. camera and filtered Cr Ka radiation standard least-squares methods were used.

A plot of peak height intensity vs. temperature for the 720 cm" band is shown in Figure 23. In this figure and all similar ones, the data is normalized to the lowest temperature measurement and is offset for clarity. The slow-crystallized sample shows a continual rise of intensity starting at the yn relaxation, ca. 110 K. This increase ends at approximately Tg(U) or 240 K. The isopentane-quenched sample, however, remains essentially constant in intensity until rg(U), whereupon it also shows a decrease. After the quenched sample is annealed, the intensity has minor fluctuations at yn and in the upper glass transition region. 

IV.la) Natural Isotopic abundances An element can be definitively identified if its correct isotopic abundance is found, either directly or indirectly after peak stripping. For instance, the peak height intensities in the 92-100 mass range in Fig. 17 closely match the abundance ratios of the... 

Peak height (intensity) is a measure of the amount of a particular metabolite. Often changes in peak height also indicate changes in the physiological condition which is a crucial point in using the method.
