摘要：

Chemical shift assignments in H-1 nmr spectra of four tricarbocyanines have been made. Studies by H-1 nmr have shown a rapid acid-catalyzed proton exchange at positions 1',7' and a much slower exchange at positions 3',5' of the heptamethine chain. Base catalysis results in a slow exchange at positions 1',7' only.
