The phrase "above spectra" is not correct in standard written English.
It may be intended to refer to spectra mentioned earlier in a text, but the phrasing is awkward and unclear.
Example: "The analysis of the above spectra reveals significant differences in the absorption characteristics."
Alternatives: "previous spectra" or "spectra mentioned above".
From the above spectra, it is revealed that identical peaks are observed with both types of PA samples, i.e., TFC and TFC/MWCNT, indicating that interfacial polymerization has ensued in all of the membranes.
As compared to the above spectra, the FT-IR spectra of PNA synthesized in the presence of HCl, Fig. 1b, shows NH-stretching vibration peak centred at 3,370 cm−1 for a secondary amine.
The characteristic difference in the above spectra (Fig. 3) is that the P3HT chains in PMMA matrix demonstrate the obvious delocalized polaron absorption at ~ 660 nm indicative of the presence of substantial crystalline ordered regions of P3HT, whereas pronounced SE at ~ 700 nm in the neat P3HT film is characteristic of intrachain excitons in disordered P3HT chains [8].
Based on the above spectra, maximum fluorescence intensities' third energy band (I3) (see Figure 3) for pyrene in a hydrophobic medium (modified copolymers) was λex = 338 nm while for pure pyrene in water it was 335 nm.
But when the above spectra were compared with their precursors in literature it was clearly found that the peak at value 1680 cm−1 is absent in Figure 5 which was due to –COOH group clearly confirming that esterification took place at this position and all other peaks remained; only the intensity of the peaks changed because of some new functional groups added in it.
Above spectra show the changes in the integral intensity of OH band and accompanying slight shift of band towards the higher frequencies in the range of 0 1440 min of time with spectra acquisition every 30 min.
In a separate processing effort, we truncated the 13Cα dimension of the above spectrum after reconstruction to obtain a digital resolution of ~42 Hz (corresponding to 72 complex points and zero filled to 128 points).
The spectrum of particles accelerated at the termination shock is then determined using the above spectrum as a source in the steady state diffusion convection equation.
All of the above spectrum sensing techniques operate with the objective of assessing spectrum utilization where the focus is on estimating the noise variance in order to determine the optimal detection threshold.
All the above heteronuclear spectra were recorded using a BIRD pulse for suppression of protons bound to 12C [30].
On the other hand, the infrared spectrum of plasma-synthetized sample contains features around 650 cm−1 and in the range 1100 1200 cm−1 that are neither seen in the above two spectra, neither before drying the solvent (not shown).
