The orientation axis depends on temperature which may originate from a conformational change of 1. A refined analysis of the ACD measurements is given and applied to 1 because all coordinates of the order tensor are known. The order of the molecules as calculated from 2H NMR spectra is higher than that obtained by UV and IR spectroscopy. The estimated electric dipole/electric quadntpole contribution to the ACD is in the order of magnitude of the electric dipole/magnetic dipole contribution.
