✦ Synopsis

The r3C chemical shieIding tensors in P sir@ crystal of@pdnol clathrate with trapped methanol molecules have been obtained by hi& resolution double resonance-A single shieIding tensor instead of three for the trapped methanol molecule results from time-averaging. It is axially symmetric ltbout the crystallographic c-axis and the anisotropy is about 0.29 times zts huge z!s that of poIycrystallinc metbartol. These results su,-est a ne.w type of motion of the trapped molecules.

For the I~-quinol (Qo) clathrate in the framework of an empirical force field model, the most suitable set of potential functions, AMBER, has been selected. The main structural and physical properties of the Q~ clathrates -the formation energy, the arrangement and barriers of rotation of the guest m
