FIGURE 18.NIR spectra at high, middle, and low positions of a V-blender after 20 minutes of mixing. At each interval, the relative standard deviation (RSD) of the NIR results at a wavelength specific to the active component was calculated. In addition, parallel HPLC analysis of the blend ...
Measured widely step-tunable mid-IR spectra In the experiment, the measured mid-IR spectra are closely related to the HBr pressure and pump power. When pumped by any absorption line wavelength, both R-branch and P-branch laser lines should have been observed from the same upper level according...
The acquisition of FTIR spectra is much faster than by conventional dispersive instruments. The FT method produces spectra that show a much better signal-to-noise ratio and, as the wavelength scale is calibrated with a very precise reference laser, provides higher waveleng...

respectively. For the reference electrode, Ag/AgCl (3 M NaCl) was used. The working electrode was prepared by spraying catalyst ink, which is used for MEA, on a carbon-coated Kapton film. The XANES spectra were collected at an angle of 45° with respect to the detector and beam line...

Earlier, data have been published on the assignment of absorption bands in the IR spectra of 5-methyltetrazole [3, 4], 5-phenyltetrazole [5], and aminotetrazole [6, 7], but they bear a rather general character and contain no information on the potential energy distribution (PED) of ...
