Using transient techniques, the free induction decay time T_2 and the spin-lattice relaxation time T_1 were measured for Br^<79> and Br^<81> in NaBrO_3 at room temperatures. The free induction decay curves were well described by Gaussian curves with T_2 = 10.2 × 10^<-5>sec for Br^<79> and 9.8 × 10^<-5>sec for Br^<81>. Comparison was made with the result of the steady-state measurement. The measured values of T_1 were 2.1 × 10^<-3>sec for Br^<79> and 3.0 × 10^<-3>sec for Br^<81>. The agreement of the ratio T_1(Br^<81>)/T_1(Br^<79>) = 1.4 with the known ratio Q^2(Br^<79>)/Q^2(Br^<81>) = 1.44 indicates that the quadrupole relaxation is principally responsible for spin-lattice relaxation. The apparatus and procedures are also described in some detail.
