Figure 4A: A comparison of Tm3+-doped bicelle EPR spectra at X-band and Q-band without cholesterol. The bicelle sample temperature was ramped from 298 K to 318 K for 16 minutes time in the static magnetic field (0.64 T for X-band and 1.25 T for Q-band) and allowed to equilibrate for 10 minutes at 318 K. The bicelle spectra were first recorded at 318 K. Then the temperature was lowered to 313, 308, 303 and 298 K, and the spectra were taken after a 5 minutes equilibration time in each step.
