Abstract
The temperature dependence of the 14N nuclear quadrupole resonance (NQR) spectrum of K-TCNQ was measured from 77 to 300 K. The NQR frequency shifts with temperature can be explained by considering the effects of the thermal averaging of the quadrupole parameters and the rearrangement of the TCNQ− and K+ stacks. The 14N NQR data are consistent with the observed Peierls transition found for K-TCNQ.Keywords
