- W2001343865 abstract "This contribution reviews briefly some aspects of the electronic spectra and circular dichroism of the series of structures I, where X = C or O and n = 0, 1, or 2, and exemplifies some of the general principles outlined by Professor Mason in his introduction. To provide a qualitative interpretation of the results, the coupling between the component π chromophores will be analysed by the simplest Hückel m. o. theory. First, let us remind ourselves of the behaviour of a 1, 3-diene (I; n = 0, X = C). Figure 1 shows diagrammatically the change in energy of the π orbitals as the molecule is rotated about the 2, 3 single bond from the conformation where the two double bonds are at right angles to one another, on the left, to the one where they are in the same plane, on the right. Dienes with an intermediate angle of twist constitute a helical system that leads to a magnetic as well as an electric dipole transition moment. The right-handed helix, in the cisoid (IV) or transoid (V) arrangement, produces a positive rotational strength (Charney, Ziffer & Weiss (1965)." @default.
