Abstract
The 79Br and 127I nuclear quadrupole resonance, NQR, spectra of ortho-substituted anilinium bromides and iodides 2-RC6H4NH3
⊕ X⊖ with X = Br, I and R = CI, CN, C2H5, NH2, and NH3
⊕ X⊖ have been investigated in the temperature range 77 < T/K <420. Phase transitions occur in 2-(C2H5)C6H4NH3
⊕ Br⊖ ½H2O at Tc= 164 K. in 2-(C2H5)C6H4NH3
⊕ I⊖ at Tc = 214 K, in [1,2-C6H4(N(H,D)3)-]2⊕[Br⊖]2 at Tc = 209 K, and in [1,2-C6H4(NH3)2]2⊕[I⊖]2 at Tc = 173 K. The NQR data are discussed and compared with NQR spectra of para-substituted anilinium halides
