In other cases, a bischromophoric derivative results in an FDCD spectrum that significantly deviates from the absorbance based data. Here it is shown that the extent of fluorescence polarization, an estimate of sample anisotropy, is directly correlated with the ability to extract a meaningful exciton-coupled FDCD spectrum. nubble lighthouse pictures https://guineenouvelles.com
