摘要: Methods previously developed in this laboratory have been used to interferometrically measure the wavelengths of three absorption lines relative Hg 198 green line. The results are: P(1), 002–000 band HCN, 15 345.2887 A vacuum; R(15), 0111–000 24 700.065 R(18), 2–0 CO, 23 150.023 vacuum. P(1) line is believed an absolute accuracy 1 part 107. other two thought be 5×106.In addition, twenty-nine HCN measured P(1). these determinations 1.5×107.
