A. Razet et P. Juncar, FREQUENCY-BEAT CONNECTIONS OF IODINE LINE S AROUND 633 NM - HYPERFINE-STRUCTURE OF THE 33P(6-3) LINE, Annales de physique, 20(2), 1995, pp. 87-88
Frequency connections of different lines of the iode molecule at 633 n
m with a beat frequency technique. Spectroscopic study of the 33P(6-3)
line of the B-X electronic transition I-127(2) iodine molecule at 633
nm with a cw tunable dye laser. The uncertainty on the frequency inte
rvals measurements between the hyperfine components, of the order some
kHz, allows the determination of the differences between hyperfine co
nstants of the four principal hyperfine interactions.
