Abstract

Time-resolved (TR) attenuated total reflection infrared (ATR-IR) spectra of sorbed water into biocompatible polymer, poly(2-methoxyethyl acrylate) (PMEA), have been investigated (Figure 1). Three broad and overlapped bands around 3600, 3400 and 3200 cm-1 are observed in the O-H stretching region of water due to H-bonds (Figure 2). Time-dependent spectral variation implies H-bonds structure changes between PMEA and water. Obtained spectral set was analyzed by perturbation-correlation moving-window two-dimensional (PCMW2D) correlation spectroscopy. A phase angle description spectrum of PCMW2D correlation demonstrates spectral variation order of the O-H stretching bands, i.e., higher wavenumber band around 3600 cm-1 is predominantly before changing, then 3400 cm-1, and then 3200 cm-1.
