Dependence of nuclear quadrupole resonance parameters on temperature for para-substituted anilines
Abstract
The temperature dependence of the 14N NQR frequencies, ν, and linewidths, ΔI, have been investigated for 4-bromoaniline, 4-chloroaniline and 4-iodoaniline. Calorimetric data were taken. BKW calculations for the ν dependence and magnetic-dipole second-moment calculations were performed when the X-ray crystal data were available.
