摘要：

Magnetic ends: By measuring the distribution of distances between two spin labels it is possible to quantify the flexibility of shape-persistent molecules (see picture). It is found that even the flexibility of short oligomers is described well by the wormlike-chain model. (Figure Presented) © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
