PARA-ELECTRIC-RESONANCE STUDY OF KC1-CN-

A paraelectric-resonance study has been made of KCl: CN- over the frequency range 32-74 GHz for electric fields up to 275 kV/cm. The data can be fitted to a 111-dipole model. The tunneling parameters (in GHz) are: η=-19.45 (±2%), μ=+1.7 (±10%), and ν=-0.23 (±50%). These parameters give the zero-field splitting: 32.55, 38.45, and 46.15 GHz. The electric-dipole moment is p=0.53 D (±2%). The new tunneling parameters open the question as to the sign of the tunneling parameters. © 1979 The American Physical Society.
