7. In each unit cell, benzophenone has four molecules. All the angular dependencies of EPR and ENDOR spectra were carried out in the crystallographic abc coordinate system at ambient temperature with a Bruker ESP300/350 spectrometer (a TM mode cavity and helical coil for RF irradiation) [36]. In each crystallographic plane, two of the molecules are equivalent. Therefore, two sets of molecules exist Fig. 6 Up Left: Benzophenone molecular structure.

83 K or lower. 17 K, or lower, which is well in reach with current technology with a W-band ENDOR spectrometer operating at liquid helium temperature. The experimental conditions are given for two cases of the experiments without and with transfer of spin polarization. We may use some sort of witness operators for detecting non-classical correlation and entanglement [18, 45]. Here we use another technique available from EPR. The technique is called Time Proportional Phase Incrementation, TPPI [46].

By upgrading and customizing an available commercial spectrometer and equipping it with Arbitrary Waveform Generator (AWG), even further advanced and interesting applications will be possible. A large number of microwave frequencies with their amplitude and relative phase controlled at a desired manner have been prepared at X-band or higher bands for QC experiments on molecular spins. 2 Exchange Polarization in Between an Electron and a Nuclear Spins It is indeed an advantage of electron involved systems that a higher polarized nuclear spin can be achieved with reasonable efforts since a highly polarized electron spin is readily available in the system therefore by applying appropriate radio-frequency and microwave pulses the nuclear spin polarization can be enhanced to an electron initial polarization.
