Resumo

The A-X system of I2 has been recorded in absorption, under conditions of medium resolution, over the region 8000 – 13 400 Å. Bandheads in progressions based on v″ = 6 through 18 have been measured and assigned. A new vibrational numbering for the A state is proposed, which leads to more reliable values for the important constants of the A state: Te = 10 906 ± 3 cm−1, De = 1641 ± 3 cm−1, ωe = 92.5 ± 0.5 cm−1, ωexe = 1.20 ± 0.08 cm−1, ωeye = −0.062 ± 0.006 cm−1.
