These forms occur both in the solid state and in solution.1•2 •5 Polyproline changes its helical structure, form I to form II, through a cis-trans isomerization of the imide bond. The reverse process is also possible (form II to form 1).3 ·4 A third, more random struc- ture...
The isopropyl group—CH(CH3)2 is the simplest structure unit that contains a tertiary carbon. The coupling between the symmetric bending modes of the two neighboring methyl groups [98] leads to a characteristic IR doublet at 1390-1380 and 1372-1365 cm−1 [59]. The components of the doubl...
Described is the genus of compounds defined according to the structure: ##STR1## wherein one of the dashed lines represents a carbon- carbon double bond and the other of the dashed lines represents a carbon- carbon single bond; wherein R.sub.4 represents methyl or ethyl; wherein one of...
The proposed scenario clearly entails that the contraction coefficient of the scaffold element is concen- tration independent; this in turn implies that the structure of this element is independent of concentra- tion. Considering the behaviour observed at lower concentrations, this is difficult to ...

The structure was solved by direct and Fourier method and refined to a discrepancy index R = 0.072. The PN bond length of N-DIPP-Ala (1.60 ) was found to be shorter than that of N-DIPP-HYp (1.62 ), but these two compounds share the same value of the P = O bond distance (1.47 ...
