P peak positions

W - peak width (two theta), P - peak position (two theta) %k - percentage area under the peaks, %B - percentage area under the background.

The upper half of Figure 3.9 represents how a spherical explosive charge of diameter d produces a blast wave of side-on peak overpressure P and positive-phase duration r" " at a distance R from the charge center. Experimental observations show that an explosive charge of diameter Kd produces a blast wave of identical side-on peak overpressure p and positive-phase duration Kt at a distance KR from the charge center. (This situation is represented in the lower half of Figure 3.9.) Consequently,... 

P = exp(-(D2a) /2) with D2 the slope of the molecular weight calibration curve at the peak position of the chromatogram of the Standard. 

Next the question arises of the extent to which the resonance condition is influenced by changes in the electrolyte. From eqn. 2.22 it follows that the H.F. conductance approaches zero for a very small or very large value of k, so that by differentating l/f p with respect to k one finds a peak position at... 

In contrast, a real challenge is the analysis of scattering images from anisotropic materials, and in this subarea many scientists surrender and resort to the interpretation of peak positions and peak widths in raw data (cf. citation of P. Debye on p. 1). So after having advanced by learning how to analyze curves, in the field of anisotropic materials we are now in a similar situation as science has been in 1931 in respect to isotropic data. 

The effect of instrumental broadening can be eliminated by deconvolution (see p. 38) of the instrumental profile from the measured spectrum. If deconvolution shall be avoided one can make assumptions on the type19 of both the instrumental profile and of the remnant line profile. In this case the deconvolution can be carried out analytically, and the result is an algebraic relation between the integral breadths of instrumental and ideal peak profile. From such a relation a linearizing plot can be found (e.g., measured peak breadths vs. peak position ) in which the instrumental breadth effect can be eliminated (Sect. 8.2.5.8). 

The temperature effect on the absorption spectra is also shown in Fig. 2. One can see that the peak position and bandwidth of the P band increase with temperature, while in other bands (like the B and H bands) only its bandwidths show a positive temperature effect. It is important to note that even though the RC is a complicated system, its spectra are relatively simple and its bandwidth is not particularly broad. The above features of absorption spectra of RCs need to be taken into account when analyzing the observed absorption spectra.

By performing the Kissinger analysis [165], i.e., an analysis of the sensitivity of the peak positions, in terms of the temperature of the peak maximum, to the applied heating rate, P, the apparent activation energy, E, can be obtained from the following equation ...

The corresponding C atoms resonate in the region between 130 and 150 ppm together with all other sp -carbons of the fullerene sphere. For the 1,6-addition adduct of with (p-methoxy-phenyl)diazomethane, the peak position of the bridgehead C atoms was found by HETCOR analysis to be 138.65 ppm [110. ...
