A Spectroscopic Analysis of Poly(lactic acid) Structure
TL;DR: In this paper, a vibrational analysis has been carried out to analyze the chain conformation of poly(lactic acid) in the crystalline state, in conjunction with a normal-coordinate analysis, the Raman spectrum has yielded data regarding conformational distributions.

A spectroscopic study of phase-transition kinetics in syndiotactic polystyrene
TL;DR: In this paper, the degree and kinetics of the transformation of polystyrene films into those containing an all-trans chain conformation in solution cast poly styrene was studied, and the amount of phase transformation above the transition temperature is highly dependent upon sample morphology and therefore their thermal history.

TL;DR: A model system for the characterization of molecular recognition events in molecularly imprinted polymers (MIPs) is presented with the use of a biologically inspired, three-point hydrogen-bonding motif and a thin film polymeric matrix, which shows a 10-fold decrease in binding after polymerization.

Raman Analysis of a Conformational Distribution of Poly(ethylene oxide) and Its Model Compound in the Liquid State
TL;DR: In this paper, the isotropic Raman spectra of poly(ethylene oxide) in aqueous solution and in the melt were simulated by superposing calculated spectra resulting from a series of normal coordinate calculations performed for an ensemble of conformers.

Vibrational spectra of C2ν deuterium substituted pyridines. 4—pyridine‐2,3,5,6‐d4 and pyridine‐d5
TL;DR: Pyridine-2,3,5,6,-d4 has been prepared and the isotopic composition and label specificity of each of three preparations were verified by mass spectroscopy and proton NMR as discussed by the authors.
