Water accounts for about 70% of a cell's weight. Water is important for protein dynamics and function in living cells. However, the role of water in bio-systems is far from well understood. In this context hydrogen bonding is ...

A comparison with spectra recorded with an ordinary globar source revealed that no artifacts occurred with synchrotron radiation. A comparison of ...

The spectrum of C,HDBr' shows the presence of two isomers, indicating that the radical has an unsymmetric structure.

Its existence and infrared spectrum were established in matrix isolation experiments by Pimentel and ...

Karlstrom et ai.' have performed a quantum mechanical calculation of the ben-zene-water interaction. They found that water prefers to form a hydrogen bond to ...

The OH-stretch region revealed the distribution of water; the amide II band gave the protein distribution; the C═O stretch and C–H stretch regions showed the variation in lipids. Water and proteins were similarly distributed. Triglycerides were predominantly found in the deeper skin layers whereas free fatty acids and ceramides were more dominant in the upper layers. ATR-FT-Far-IR spectroscopy with synchrotron radiation was used on full thickness pig ear skin biopsies. The Far-IR spectra showed bands in the region from 100–150 cm–1due to hydrogen bonded proteins and a band around 180 cm–1arising from “free” water.
