The chemical shift values of cis/trans conformers
belonging to protons of benzyl CH2, N-CH2, N=CH and NH in the 1H NMR and, to carbons of benzyl CH2, N-CH2 and N=CH in the13C NMR spectra of compounds 5a-e and the percentage ratios of cis/trans conformers
are given in Table-1.
0], initially assumed to be entirely supported by such skeleton (mainly by increased intermolecular distances, but possibly also by some increased bond angles in cases of significant molecular orientation), will then gradually transfer to an increased number of "trans", and a decreased number of "gauche", conformers
as some of the chains unfold, taking as reference what may be assumed to happen in tensile and simple unidirectional shear situations; other more complex stress/strain situations are for the time excluded, and will have to be separately and specifically considered.
The solvent effect towards the conformers

of type 2 are by far statistically more valid at 300 K than conformer
types 1 and 3 (note the result of MD run: see item 2 in Table 1), i.
We developed this protocol to solve some technical difficulties arising from the application of traditional SSCP analysis for mutation detection in DNA fragments longer than 400 bp, which was unable to separate single-strand conformers
even at different gel compositions and temperatures.
This insight was derived from computer-based molecular modeling calculations that verified the existence of high-energy conformers
and showed that an energy barrier lies between the high-energy and low-energy conformers

Table-1 presents the energy calculations for the three conformers
The two stable conformers
are the trans or anti ([C.
