摘要：

Chromophores related to fluorescent proteins, when sequestered into the "octaacid" capsule, recover their fluorescence, The fluorescence recovery is related to the inhibition of torsional motions within the cavity, implicating the single-bond torsion as an important contributor to internal conversion within this important class of chromophores.
