Preface.Acknowledgements.1 Introduction.1.1 Two-dimensional Spectroscopy.1.2 Overview of the Field.1.3 Generalized Two-dimensional Correlation.1.3.1 Types of Spectroscopic Probes.1.3.2 External…
Wavelength interval selection in multicomponent spectral analysis by moving window partial least-squares regression with applications to mid-infrared and near-infrared spectroscopic data.
TLDR
It is shown that MWPLSR provides a viable approach to eliminate the extra variability generated by non-composition-related factors such as the perturbations in experimental conditions and physical properties of samples.

Crystal Modifications and Thermal Behavior of Poly(l-lactic acid) Revealed by Infrared Spectroscopy
Recently, we reported the isothermal crystallization behaviors of poly(l-lactic acid) (PLLA) from the melt and glassy states, respectively [J. Phys. Chem. B 2004, 108, 11514; Macromolecules 2004, 37,…

Temperature-Dependent Structural Changes in Hydrogen Bonds in Microcrystalline Cellulose Studied by Infrared and Near-Infrared Spectroscopy with Perturbation-Correlation Moving-Window Two-Dimensional…
TLDR
Temperature-dependent structural changes in hydrogen bonds (H-bonds) in microcrystalline cellulose (MCC) were investigated by infrared (IR) and near-infrared (NIR) spectroscopy and band assignments for the O–H stretching first overtone vibration region are proposed based on the results of the PCMW2D correlation analyses.

The detection and quantification of adulteration in olive oil by near-infrared spectroscopy and chemometrics.
TLDR
A chemometric analysis of the near-infrared spectra of olive-oil mixtures containing different adulterants revealed that the PCA developed models were able to classify unknown adulterated olive oil mixtures with almost 100% certainty.

Near-infrared spectroscopy for dairy management: measurement of unhomogenized milk composition.
TLDR
The spectral region and sample thickness were found to be significant factors for milk fat and total protein determination but not the lactose determination, and different treatments of spectral data did not improve the calibrations for fat and protein.

Study on temperature-dependent changes in hydrogen bonds in cellulose Ibeta by infrared spectroscopy with perturbation-correlation moving-window two-dimensional correlation spectroscopy.
TLDR
Results suggest that the phase transition is induced by the dissociation of the O3-H3...O5 and O2-H2...O6 intrachain H-bonds, however, the interchain H- bonds are not so much responsible for the transition directly.
