**9. CSC-temperature of MBBA in the isotropic phase**

**Figure 6A** shows the structure of MBBA and the chemical shift values for individual protons as a function of temperature for isotropic phase MBBA. It is noted

that the chemical shifts of different protons showed very different temperature variations. However, the chemical shift did exhibit a linear change as a function of the temperature for each different proton; therefore, it was possible to estimate the CSC-temperature of MBBA in the isotropic phase under microwave irradiation.
