Xe-129 NMR spectrum of xenon inside C-60
Xenon was inserted into C-60 by heating C-60 in 3000 atm of xenon gas at 650 degreesC. The Xe @ C-60 was separated from the empty C-60 by using HPLC. The C-13 resonance for Xe @ C-60 is shifted downfield by 0.95 ppm (192 Hz). Xe-129 NMR showed a line 179.2 ppm downfield from xenon gas.
