Merging spectra ranges

Spectra of the same type (e. g. absorbance spectra) can be linked together to form a new spectrum. Any gap in the wavenumber region is filled with a straight line. If two spectra to be merged overlap, linear weighting is per-

To illustrate the merging procedure, consider the Raman spectrum of stratum comeum. There are two spectral regions of interest, namely between 600 and 

1800 cm and between 2700 and 3200 cm. Therefore, let us generate two separate spectra by cutting the corresponding ranges and then merge them. The resulting spectrum is shown in Fig. 10.61.

The relative success of the binary encounter and Bethe theories, and the relatively well established systematic trends observed in the measured differential cross sections for ionization by fast protons, has stimulated the development of models that can extend the range of data for use in various applications. It is clear that the low-energy portion of the secondary electron spectra are related to the optical oscillator strength and that the ejection of fast electrons can be predicted reasonable well by the binary encounter theory. The question is how to merge these two concepts to predict the full spectrum. 

Figure 4. Splicing partial interferometer and monochromator spectra of glycerol. Interferometer spectra, obtained with three different instrument settings (FSR= 15, 75, 300 GHz), together cover the range 0.4 GHz through 300 GHz. Monochromator spectra, obtained with two different instrument settings, cover 100 GHz through 50 THz. Merging the partial spectra produces a composite spectrum covering some five decades in frequency. (Adapted from Ref. 64.)...

The same authors presented an MD study of the molecular dipole moment and a net charge for [C4mim]+ combined with BFJ, [DCA] and the trifluoromethyl-acetate [89], In contrast to a solution of simple ions in a (non)polar solvent, rotational and translational effects were found to play a role. The theoretical framework necessary to compute the conductivity spectrum and its low frequency limit of ILs was newly developed. Merging these computed conductivity spectra with previous simulation results on the dielectric spectra resulted in the spectrum of the generalized dielectric constant [89], It was calculated for the three ILs over six orders of magnitude in frequency ranging from 10 MHz to 50 THz [89],... 

Further evidence for the presence of defect sites and V-ions in the framework of sample B comes from the Si NMR spectra of the samples (Fig. 4). The Si NMR spectrum of the calcined sample B reveals a resonance attributable to defect silanols at 5 = -100 to -110 ppm which is not observed in the spectrum of A. Besides, the bands due to Q -Si observed in the range of 5 = -110 to -120 ppm are merged without resolution leading to a broad band in the spectrum of B, while they are better resolved in the spectrum of A. The broadness and the lack of resolution of the lines in the spectrum of B may be an indication of the statistical distribution of the V in the lattice.
