Apparent spin–spin relaxation time T *2 for an aged single crystal of p-dichlorobenzene using a superregenerative spectrometer
Abstract
The nuclear quadrupole relaxation parameter T*2 has been measured for a single crystal of p-dichlorobenzene (α-phase) at 293 and 77 K using the detection threshold quench frequency shift technique and a superregenerative oscillator. The results are compared with those from polycrystalline samples.
