    Notes: [Auszug] THE results described by Chakrabarti and Nodder in their communication entitled “Some Effects of the Helical Fibrillar Structure of Vegetable Fibres”1 appear to be based on incorrect fibrillar arrangements. The following comments on the observed effects are, therefore, offered in ...

    Notes: 13C NMR data for 1,6-bis derivatives of hexa-2,4-diynes are reported. Introduction of a sulphone or sulphoxide moiety at C-1, C-6 in place of sulphide, ether or amino groups caused a 6-7 ppm upfield shift (β effect) for the C-2, C-5 carbons and a 3-4 ppm downfield shift (y effect) for the C-3, C-4 carbons.
