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 ExternalExpand
Wavelength interval selection in multicomponent spectral analysis by moving window partial least-squares regression with applications to mid-infrared and near-infrared spectroscopic data.
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. Expand
Temperature-Dependent Structural Changes in Hydrogen Bonds in Microcrystalline Cellulose Studied by Infrared and Near-Infrared Spectroscopy with Perturbation-Correlation Moving-Window Two-Dimensional
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.

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,Expand
The detection and quantification of adulteration in olive oil by near-infrared spectroscopy and chemometrics.
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. Expand
Near-infrared spectroscopy in food science and technology

Near-infrared spectroscopy for dairy management: measurement of unhomogenized milk composition.
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. Expand
Principles and methodologies in self-modeling curve resolution
This review paper aims at examining the recent developments in self-modeling curve resolution (SMCR). Particular emphasis is put on the progress in methodologies for SMCR. A historical review isExpand
Study on temperature-dependent changes in hydrogen bonds in cellulose Ibeta by infrared spectroscopy with perturbation-correlation moving-window two-dimensional correlation spectroscopy.
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. Expand
A Study on Water Adsorption onto Microcrystalline Cellulose by Near-Infrared Spectroscopy with Two-Dimensional Correlation Spectroscopy and Principal Component Analysis
It is revealed from the present study that approximately 3–7 wt % of adsorbed water is responsible for the stabilization of the H-bond network in MCC at the cellulose–water surface. Expand
