53. The MMX program places a positive charge on the N atom of the C-N≡C group due to the tetravalent nature of the atom. As a result the program computes electrostatic interactions and the C⋯C separations (bite distances) > 5.2 Å. By replacing the isocyano groups by cyano or acetylene (-C≡C-H) the bite distance decreases to ∼5 Å.

63. The criteria used to decide the number of components necessary to describe the data is based on the first best fit where all the data points are reasonably well fitted, going from a mono-, to bi-, to tri-, and to tetraexponential analysis. These results indicate that the polymeric nature of the materials clearly influences the excited state deactivation pathways.

65. 45 In these cases two very distinct emission bands were observed, one of which was related to the end-of-chain species, and the other one to middle chain. This is not the case here.
