At q>i = (pu the polarization PA vanishes and the only spectral line of symmetric collective excitations is observed. At spectral lines (the former corresponding to the lower frequency) which arise from the splitting is given by the ratio of the corresponding polarizations (see Eqs. (3.3.4) and (3.3.5) at 0= 90°) ...

However, the detailed studies of NMR spectra led to the conclusion about the interchange of apical and equatorial fluorine atoms. Since the apical and equatorial bonds P—F in PF5 have different lengths, the NMR spectrum can be expected to consist of two doublets with integral intensity ratio 2 3. Actually, the observed NMR spectrum of PF5 (at F) has one doublet caused by spin-spin interaction of P and F nuclei, i.e. the splitting of signals from axial and equatorial fluorine atoms is absent.

Comparing these equations with Eqs. (13-1), we note that only the superlattice lines are affected. But the effect is a strong one, because the intensity of a superlattice line is proportional to F and therefore to S. For example, a decrease in order from S = l.(X) to 5 = 0.84 decreases the intensity of a superlattice line by about 30 percent. The weakening of superlattice lines by partial disorder is illustrated in Fig, 13-3. By comparing the integrated intensity ratio of a superlattice and fundamental line, we can determine S experimentally. 

Where X is the integrated intensity ratio, and P =1.340 Here and I, are the peak heights of in-ZrOj and t-Zr02. 

The H NMR spectrum of pyridine shows three signals with the integral intensity ratio of 2 1 2, which correspond to the three chemically different protons in the molecule a-protons (chemical shift 8.6 ppm), y-proton (7.7 ppm), and P-protons (7.3 ppm). The a- and y-protons are further downfield in comparison to the P-protons because of the lower electron density in the a- and y-positions, which can be derived fi om the resonance structures. The coupling constants of the pyridine protons are usually similar to those of benzene, except for the coupling constant between the two a-protons being reduced from 7-8 Hz to 4-6 Hz. 

These solutions generate a single CN band centered at 2059 cm and it was assumed, therefore, that the stoichiometric salt concentration was equal to the "free" SCN" concentration. Relative integrated intensity ratios Ip (A2059M93i) CqOa plotted... 

The integrated intensity ratio of the D and G peaks (/d/1g) has been often used as an indication of the level of chemical functionalisation or defect density on carbon nanotube surfaces. This ratio is much larger (7d//g = 1-6) for GE-2 compared to GE-1 (7d/7g = 0-54), indicating a more defective surface for GE-2. For GE-1 the 7d/7q ratio increases from 0.54 to 0.7 upon O2 plasma etching, indicating that the defect density increases. This increase in defect density is also shown by G line broadening. For GE-2 the 7d/7g ratio reduces from 1.6 to 1.2, which gives the false idea of a...

Pearson noted that an antisymbiotic effect is also operative and explained this on the basis of a trans influence two soft Ugands in mutually trans positions will have a destabilizing effect on each other when attached to soft metal atoms. Linearly dicoordinated LAu(CNS) complexes exemplify this effect. (Hereafter, CNS represents the thiocyanate ligand without specifying the coordination mode.) Although only the S-bonded isomer of each complex is present in the solid state, the N-bonded isomers of some complexes were found to coexist in a variety of solvents. The Au— NCS/Au—SCN ratio determined as the integrated intensity ratio of the v(CN) absorption increases... 

The ratio of integral intensity of D and G bands gives access to calculate two important parameters for free carbon phase, namely the lateral size of carbon (or crystallite size for graphite) as well as the inter-defect distance L. The shape profile of 2D band as well as the integral intensity ratio of I(2D) to 1(G) provide information on the stacking number of graphene layers (Gao, 2012).
