The UV-visible optical absorption spectrum
of pure PVA and PVA/PDAP composite are .
Common 4-ketocarotenoids cannot account for this shoulder because they have a unimodal absorption spectrum
centered ~460 nm in the solvent system we used, pointing to the presence of a red pigment that absorbs at longer wavelengths than common 4-keto-carotenoids.
As seen, the shape of the absorption spectrum
of PPME resembles that of PPa with two strong absorption vibronic bands centered at 412.
All biological systems have a unique absorption spectrum
If Beer's law is obeyed for all the compounds over the whole wavelength range used and the path-length is 1cm, the absorption spectrum
of the mixture is defined by the equation:
A comparative study of IR absorption spectrum
for carbon nano-tubes unmodified with the same IR absorption spectrum
for carbon nano-tubes plated with iron (III) oxide (fig.
s] and the structure is a mirror image of the absorption spectrum
shown in Fig.
The other tablet excipients usually present during compounding are not likely to interfere with the absorption spectrum
of artesunate (Fig.
The result would be a yellow tint from the additive's absorption spectrum
Addition of the cationic surfactant CTAB resulted in a 6-fold increase in polymer fluorescence intensity and a narrowed, blue-shifted polymer absorption spectrum
, suggesting that interaction with surfactant helped to break up polymer aggregates.
Plotting the strength of the detector signal over time provides an absorption spectrum
for the sample, which can be compared against the known absorbance of specific molecules.
They provide a peak wavelength that is equal to the absorption spectrum
of most plastics, according to Heraeus.
Oxygen-deuterium bonds in the gem's water molecules absorb specific wavelengths of the light, yielding an absorption spectrum
that serves as an optical signature.
The aim of multivariate regression methods is to correlate variations in blood FT-IR absorption spectra with the known changes in the absorption spectrum
of a pure component when the concentration of the pure component varies within samples.
Due to structural and electronic reasons, the absorption spectrum
of the dimer differs drastically from that of the monomeric species.
