Zeeman effects of <SUP>63</SUP>Cu and <SUP>81</SUP>Br NQR spectra of bis(triphenylphosphine)copper(I) bromide, CuBr(PPh<SUB>3</SUB>)<SUB>2</SUB>, have been studied at room temperature. The asymmetry parameters and the quadrupole coupling constants (<I>e</I><SUP>2</SUP><I>Qq</I>⁄<I>h</I>) have been found to be 0.113 and 64.58 MHz for <SUP>63</SUP>Cu and 0.518 and 105.91 MHz for <SUP>81</SUP>Br. The large asymmetry parameter of the <SUP>81</SUP>Br NQR line is caused by the π-bonding character of the copper-bromine bond. The bonding scheme between the copper and bromine atoms is discussed on the basis of the obtained directions of the electric field gradient axes.
