Two-Dimensional Fourier Transform Near-Infrared Correlation Spectroscopy Studies of Temperature-Dependent Spectral Variations of Oleyl Alcohol

Two-dimensional Correlation Gel Permeation Chromatography (2D GPC) Study of Aggregate–Aggregate Interactions during Polymerization of 3-(Triethoxysilyl)propyl-terminated Polystyrene

“…In general, in the earlier polymerization process of silicic acid monomers, Si(OH) 4 , the condensation reaction leads quickly to ring structures (e.g., the cyclic tetramer), 30,32 which condense internally to a compact state with the SiOH groups remaining on the surface. This concept may be modified to conform to the growth process of the polymeric aggregates of TESiP-PS.…”

“…[4][5][6][7][8][9] It is therefore expected that this technique could also become a potential tool for studying the details of reaction dynamics and mechanisms in a polymerization process.…”

In situ near-infrared spectroscopic studies of the structural changes of polyethylene during melting

“…Barton and Noda et al [5][6][7][8] also assigned NIR bands by correlation with IR bands using two-dimensional correlation spectroscopy. Ozaki et al and Siesler et al [9][10][11][12][13][14][15][16] recently demonstrated that NIR spectroscopy can be useful for the structural characterization of polymeric materials, foods and bio-based materials.…”

Two-dimensional infrared correlation spectroscopy of synthetic and biological apatites

“…Recently, a generalized two-dimensional correlation method (2D IR) has been developed for IR spectroscopic analysis by Noda and associates. [16][17][18] A full review of the theory and applications is provided e l s e~h e r e .~~~~~ Differences in band parameters, such as intensity, position, and/or halfwidth in a series of spectra related by an external perturbation having an arbitrary waveform are correlated with such changes at any other frequencies in the spectral series. The analysis produces 3D plots with two spectral frequency axes and an intensity axis.…”
