Résumé
We used infrared-visible sum-frequency generation spectroscopy to investigate the vibrational properties of the
water/poly(ethylene glycol) interface in the 2800±3800 cm'1 spectral range. The vibrational ¯ngerprint of the interface
di€ers signi¯cantly from the one associated with the air/poly(ethylene glycol) interface. It is shown that the poly(ethylene
glycol) molecular arrangement, originally relatively well-ordered, becomes disorganised in the presence of water.
Moreover, a new OH band is identi¯ed demonstrating the strong interaction of water with the polymer.
