Notizen: [Auszug] The phenomenon has been further investigated by infra-red spectroscopy. The fundamental hydroxyl stretching frequency of the water absorbed by the compounds mentioned has been recorded, and the spectrum due to the absorbate eliminated using a double beam technique. The following facts were ...

Notizen: Isotherms have been obtained for the absorption of water by proteins and polyamides and by simple amides closely related to the repeat chemical unit of the polymers. The differential heat of absorption of water at zero water content has also been determined for these substances, from isosteres and from heats of mixing. In addition the nature of the hydrogen bonding of water to these compounds has been investigated by infrared spectroscopic methods. The large differences found between the heats of absorption by the polymers and the simple model compounds are discussed.
