In ortho-methylthiobenzophenone the unsubstituted phenyl group is nearly coplanar with the thiocarbonyl group, whereas the o-tolyl group is not. The phenylthiocarbonyl absorption band shifts upon introduction of meta-and para- substituents according

The shifts in the CS stretching vibration caused by various substituents in thiobenzophenone are so small that no good correlations between substituent constants and absorption frequencies is found. Differences between the n.m.r. spectra of thiobenzo

The current view of dietary carbohydrates as simply providing us with energy is outdated. Because of their varied chemistry and physical form the rate and extent to which the different types are digested in and absorbed from the small intestine varie
