40. The defects described in this paper have the following meaning: end-gauche, a single gauche C-C bond on the end of an all-trans methylene chain; internal kink, a single gauche C-C bond in an otherwise all-trans chain; double-gauche, two sequential gauche C-C bonds either at the end of or in an all-trans chain.

44. -1 can only be considered tentative due to the lack of a viable model system. It is likely that seme of the bands in this region arise from defect structures, such as the end-gauche conformer (see below). However, we feel it is better to err on the conservative side and only assign obvious bands to defect modes.
