The structure of the line λ = 613.4 nm (6P3 2P°⅔ − 7s 2P⅔) in Bi I has been completely analyzed by means of a Fourier-transform spectrometer. From the intensity calculations it is seen that only 9 components of the possible 10 can be observed. The A and B constants are also calculated and compared with earlier results. The values of the levels 7s 2P⅔ and 6P3 2P°⅔ have been recalculated to be 49 460.91 ±0.01 and 33 164.82 ±0.01 cm−1, respectively.
