The state of sorbed water and sorbing processes of water to four kinds of vinyl polymer films were studied by FT-IR. The O-H stretching band of water sorbed to the films gradually increased on contact with a water vapor of 50% relative humidity at 25 โข C and leveled off. The profile of the O-H stret

High-pressure FT-IR spectroscopy was used to study a W/O microemulsion system of AOT micelles dispersed in supercritical ethane. The system was found to be in a single-phase state depending on the pressure (P), temperature (T), and water-to-AOT molar ratio (W0). The number of water molecules that th
## Abstract The structure and hydrogen bonding of water incorporated in a thin film of amphoteric terpolymers composed of various ratios of MA, DMAPMA, and BMA were analyzed using the band shapes of the O๏ฃฟH stretching in the IR spectra. At an early stage of sorption of water, the IR spectrum for th
Copper,zinc superoxide dismutase (Cu 2 Zn 2 -SOD) from bovine erythrocyte and its metal ion free derivatives, E 2 Zn 2 -SOD, Cu 2 E 2 -SOD, and E 2 E 2 -SOD (E: empty) were prepared and their secondary structures were investigated by Fourier transform ir spectroscopy. In 20 mM deuterated phosphate b
