The theory of pure spin-1 nuclear quadrupole resonance (NQR) excitation and detection is presented with comparisons to nuclear magnetic resonance (NMR). Even though the dominating Hamiltonians in pure NQR and NMR have different symmetry properties, in both single resonant frequency spin-1 NQR and spin-(1)/(2) NMR the spin dynamics are isolated to two resonant energy levels, leading to close parallels in the calculations of their respective signals, The theory of spin-1 NQR is presented in terms of matrix calculations and fictitious spin-(1)/(2) operators, and the analysis focuses on the similarities and differences of the spin-1 NQR and spin-(1)/(2) NMR physical interpretations and rotational symmetry properties.
