Caracterización dinámica de la fase vítrea en clorotolueno
(2017-03)
En el presente trabajo se presentan resultados experimentales que permiten caracterizar dinámica y estructuralmente las fases sólidas encontradas en el p-clorotolueno y el o-clorotolueno a temperaturas mayores a 80 K. La ...
A model to describe the inhomogeneous broadening of NQR lines in chlorohalobenzenes with orientational or substitutional disorder
(Academic Press Inc Elsevier Science, 2017-10)
A simple model to explain the NQR lineshape in solids with orientational disorder or substitutional disorder is presented. The particular case of m-chlorobromobenzene is studied. It is based on the assumption that Bromine ...
Magnetic resonance study of the crystallization behavior of InF3-based glasses doped with Cu2+, Mn2+ and Gd3+
(2006-09-15)
The crystallization of fluoroindate glasses doped with Gd3+, Mn2+ and Cu2+ heat treated at different temperatures, ranging from the glass transition temperature (Tg) to the crystallization temperature (Tc), are investigated ...

T4 dependence of the nuclear quadrupole resonance frequencies in solids. II
(1973-01-01)
Analyses of experimental data for NQR frequency shifts as a function of temperature reveal a dominant T4 dependence at sufficiently low temperature, T ≲ 20°K, in accord with a recent prediction. The results indicate the ...
