摘要:
Conformation sensitive bands are found in the sub-800-cm(-1) region of the IR and Raman spectra of an imine-type oligoaniline, 1. This allows the determination of the conformation in the powder sample (obtained by the Zaghal-Shatnawi procedure) to be predominantly nonplanar E; the abundance of the Z conformer with similar energy is about 5%.
