(A) Frequency dependence of 1/T1 ( ) for 26DTBSQ in ethanol at 293 K. The relaxation is modeled as the sum (- -, short dash) of contributions from spin rotation (SR) (—, solid) Eq. (2), a local mode (local) (— —, long dash) Eq. (3), modulation of g-anisotropy (— - - -, dash dot) Eq. (5), and modulation of dipolar interactions with solvent nuclei (solvent) (– –, medium dash) Eq. (8). (B) Frequency dependence of 1/T1 in C2H5OH ( ) and in C2H5OD (○). The dashed lines through the data are the sums of contributions to the spin lattice relaxation as described in the text and calculated with Eq. 2, 3, 5, and 8.
