The Doppler-limited absorption spectrum of the vib-rotational lines in the A^3II_<1u>←X^1Σ^+_g system of I_2 was measured in the region from 11650 to 12300 cm^<-1> using a Ti : sapphire ring laser. The Q-branch lines of J=10 to 100 belonging to the v'←v"=29'〜31'←O", 21"〜30'←1" and 22'〜31'←2" Progressions having no hyperfine splittings were assigned, and the values of ν^0_Q, B'_<vf>-B"_v, D7_<vf>-D"_v and H'_v-H"_v, were determined using a least squares fitting procedure. The calculated line positions of the Q-branches agreed with those observed within the accuracies of the wave-number measurements of 0.005 cm^<-1>. By using the Dunham expansion parameters of the X-state reported by Tromp and Le Roy, the spectroscopic constants of T'_v, B'_<vf>, D'_<vf> and H'_<vf> suitable for v'=21'〜31' in the A-state were calculated by a global least squares fitting procedure.
