## Abstract The effect of impurity (__p__βtoluidine) on the nuclear quadrupole resonance of two different nuclei (^35^Cl and ^14^N) in the same molecule has been studied. The ^14^N resonance is unaffected whereas the ^35^Cl resonance is greatly reduced.
The reorientation of CClF, groups in N(CH,),H(ClF,CCOO), has been studied using pulsed NQR and NMR techniques. The temperature dependence of both chlorine ("'Cl) NQR and fluorine ('"F) NMR spin-lattice relaxation has been measured T,, of chlorine is attributed to the sum of two contributions: the re
A comprehensive collection of the applications of Nuclear Magnetic Resonance (NMR), Magnetic Resonance Imaging (MRI) and Electron-Spin Resonance (ESR). Covers the wide ranging disciplines in which these techniques are used: * Chemistry; * Biological Sciences; * Pharmaceutical Sciences; * Medical use
