Abstract

We have extended our previous work (Torres et al., 2022) by performing absorption laser spectroscopy of I2 in the 14400-14600 cm-1 range, using a narrow linewidth diode laser, whose frequency is actively measured using a calibrated wavelength meter. In this range, we have observed 1204 reference lines, 417 more lines than Salami and Ross (2005). The remaining lines are in good agreement with the works carried out by Gerstenkorn and Luc (1979) and by Salami and Ross (2005). The spectrum predicted by the software Iodine Spec5 reproduced our results very accurately. (AU)
