| Abstract: | 82 , Y@C82, and La@C82 in frozen solutions. We were able to determine the g tensors of these molecules by analysing magnetic field spectra at X-band
(9.5 GHz) and W-band (94 GHz) frequencies. Moreover, in Y@C82 we have investigated the hyperfine interaction of the 89Y nuclear spin (I=1/2) with the electron spin on the C82 cage. The principal values of the hyperfine tensor A and the relative orientation of g and A tensors were determined by applying
three- and four-pulse electron spin echo envelope modulation techniques (ESEEM).
