137BaCl 2 · 2H 2O: Temperature study of the nuclear quadrupole resonance frequencies and apparent spin-spin relaxation times using a super-regenerative oscillator on 137Ba using the coherent mode

Abstract

The 137Ba nuclear quadrupole resonance frequency υ and apparent spin-spin relaxation time T 2 * of 137BaCl · 2H 2O were measured using a self-quenching superregenerative oscillator between room temperature and liquid nitrogen temperature. The T 2 * were recorded using the spectrometer in the coherent mode.
