The Temperature Dependence of the N-14 NQR Spectrum, Relaxation Times, and Line Shapes of Cyanuric Fluoride

Abstract

Measurements of the N -14 NQR spectrum, relaxation times, and line shapes as functions of temperature of cyanuric fluoride are reported. This material exhibits very wide lines and thus lends itself to determining the profile of the lines from measurements of the echo heights. The material also exhibits a phase transition similar to that found in s-triazine. The phase transition occurs at 115 ± 5 K. A comparison of the results is made with those obtained previously for cyanuric chloride and s-triazine.
