Figure 4. Dependance of spin relaxation times on the effective SOC.

(a) Spin lattice relaxation time versus Δg for all measured molecules. Error bars represent 95% confidence intervals. Dashed line shows the expected proportionality T₁∝(Δg)⁻² for relaxation via SOC fields. (b) Spin coherence time versus Δg for all measured molecules. Error bars show the 95% confidence intervals. (c) Dependence of T₁ and T₂ on the correlation time τ_C of field fluctuations from the Redfield theory. Model values of ω_L/2π=9.4 GHz and were used for the plot. (d) Correlation times τ_C as estimated from the Redfield theory and plotted against rotational correlation times obtained from DOSY NMR diffusion constants (when available). Error bars from 95% confidence intervals of T₁ and T₂ and error propagation.
