✦ Synopsis

A high precision dense grid of reference lines in the hyperfine structure of the B-X system of molecular iodine ( 127 I 2 ) is presented. A simple parametrization has been derived, predicting the hyperfine line positions of the ''t'' components for vibrational bands (13-1) up to (18-1) and rotational quantum numbers J Å (9-140). The analysis in this paper is based on Doppler-free saturation spectroscopy spectra used for calibration of more than 100 new components in the hyperfine structure of 127 I 2 . The data presented contains a prediction (with 2 MHz accuracy) for the positions of 1584 ''t'' components in the rotational structure of iodine, covering the wavelength interval 571-596 nm.
