Charge separation elongation

Li, K. et al. [60]Fullerene-stoppered porphyrinorotaxanes Pronounced elongation of charge-separated-state hfetimes. J. Am. Chem. Soc. 126,9156-9157, 2004. 

During studies on the interaction between sulfur donors and suitable acceptors, the solid-state structure of the charge-transfer adduct l,3-dithiane-2-thione- -diiodine 111 was investigated <1999IC4626> the CS3 moiety is planar, the I2 molecule lies in the same plane with the first iodine atom separated by 2.755 A and the I-I vector is practically co-linear with the S-I one. The I-I bond length is slightly elongated with respect to a free iodine molecule. 

It should be noted that loose BkPdr charges were used until about the middle of the 16th century. Then the BkPdr was placed in a paper bag, as shown in Fig A, while the bullet remained to be loaded separately. The next step (ca 1590) was incorporation in the paper bag (cartridge) a wad or plug and a round bullet as shown in Fig C. Still later the bullet was elongated and pointed at the nose as shown on Fig B...
