Mozzhukhin, J. Barras, G. Kupriyanova, B. Rameev] Two possible modifications of two-frequency 14N nuclear quadrupole resonance (NQR) technique for the identification of resonance lines in NQR spectra have been studied and compared. The first one is the use of a single coil for two close frequencies (in our case, ν + and ν − lines), while the second one utilizes two coils for two different resonance frequencies. Both two-frequency methods have been applied to the carbamazepine which is a substance with a low asymmetry parameter η of the electric field gradient tensor in crystal. It has been shown that both approaches can be applied for the identification of the 14N NQR lines. Springer-Verlag Wien, 2014 Mozzhukhin G.
