Abstract
We used infrared-visible sum-frequency generation spectroscopy to investiga
te the vibrational properties of the water/poly(ethylene glycol) interface
in the 2800-3800 cm(-1) spectral range. The vibrational fingerprint of the
interface differs significantly from the one associated with the air/poly(e
thylene glycol) interface. It is shown that the poly(ethylene glycol) molec
ular arrangement, originally relatively well-ordered, becomes disorganised
in the presence of water. Moreover, a new OH band is identified demonstrati
ng the strong interaction of water with the polymer. (C) 2001 Elsevier Scie
