Abstract :
Within the Nd laser tuning range, modulation transfer spectroscopy recovers nine strong ro-vibrational transitions of /sup 127/I/sub 2/ molecules with excellent signal-to-noise ratios. These transitions are now frequency-linked together, with their absolute frequencies referred to the R(56)32-0:a/sub 10/ component. Hyperfine structure splittings for the two "new" lines are fit with residuals /spl sim/500 Hz.
