摘要	In this paper, we report a precision measurement of hyperfine splitting and absolute frequency of D-1 line in cold Li-6 atoms. The gray molasses is realized in the experiment and the tempreature is cooled to about 50 mu K, which is lower than the Doppler cooling limit, 140 mu K. By use of an optical comb, the absolute frequencies and corresponding hyperfine splitting are measured. We obtain frequencies of 446789503.080(35) MHz, 446789529.198(36) MHz, 446789731.316(50) MHz and 446789757.476(29) MHz for the D-1 line. The results are in reasonable agreement with the theoretical calculations and consistent with earlier measurements. They could provide an important foundation for future frequency measurement, alpha constant and nuclear radius.
