| Abstract: | 80 , Ca/Sr/Ba@C82, Ca/Sr/Ba@C84) are investigated for the first time by UV-Vis-NIR absorption spectroscopy and high-resolution 13C NMR. Direct evidence of the endohedral nature and cage structures are revealed by these measurements. Furthermore, we have
found that each metallofullerene has 2–4 structural isomers, which have been isolated by multistage high-performance liquid
chromatography. These isomers have different cage structures and give characteristic UV-Vis-NIR absorption spectra.
