Abstract We have obtained the Raman spectra of the calix[n]arene C60 complex of anti-conformation. Very different interactions between C60 and calix[n]arene (n = 4,8) have been found from the vibratory spectroscopy, which are more complicated than that reported in previous works. It is of interest to find three low frequency modes, i.e., the spheroidal, torsional and E2 clearly shown at 39, 130 and 208 cm-1, respectively. It is primarily interpreted as relaxation effect of calix[8]arene framework for C60 where the intramolecular bridge between C60 and calix[8]arene are partly packed and two axes of C60 ([100] and [101]) are changed from the original configuration. The change of vibratory environment of carbon atom of C60 made some new modes create. The Hg5 mode (at 1101cm-1) and Hg2 (at 431cm-1) have been split and some modes (the Ag2 and other six Hg modes) were hidden.
