The effect of concentration on the observed spectrum shows an isobestic point, suggesting an equilibrium between two species. The possible mechanisms for such a transformation are discussed.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000173721800016</style></accession-num><notes><style face="normal" font="default" size="100%">Landes, C Braun, M Burda, C El-Sayed, MA</style></notes><electronic-resource-num><style face="normal" font="default" size="100%">10.1021/nl015619t</style></electronic-resource-num></record></records></xml>
