发现长链全氟化羧酸盐在205-225纳米区域比全氟乙酸盐具有更强的电子吸收带。在某些区域，吸收率随着胶束的形成而显著增加。这种增加可用于确定全氟化羧酸盐在水溶液和存在高浓度氯化物盐的情况下的临界胶束浓度
Long-chain perfluorocarboxylates have been found to have stronger electronic absorption bands in the 205-225-nm region than perfluoroacetates. The absorptivity increases significantly on micelle formation in some regions. This increase can be used to determine critical micellization concentrations (cmc) of perfluorocarboxylates in aqueous solutions and in the presence of high concentrations of chloride salts
