Spectroscopic analysis reveals electronic transitions and vibrational structures in molecular fluorine, indicating a precise ground-state dissociation energy of 12 920 cm⁻¹.

Key Points

To conduct a detailed rotational and vibrational analysis of the electronic absorption and emission spectra of molecular fluorine (F2).
Photographed high-resolution absorption spectra of F2 in the 780–1020 Å range to enable rotational analysis of multiple bands.
Recorded and analyzed the 1Σu+ – X 1Σg+ emission band system in the 1100 Å region for ground-state vibrational levels up to ν ≤ 22.
Identified vibrational levels and rotational constants for three interacting ionic states, determining their rotational perturbations and interaction energies.
Characterized rotational and vibrational structures of several Rydberg states and resolved ground-state term values and rotational constants for ν ≤ 22.
Established the dissociation energy D0(F2) to be greater than 12 830 cm⁻¹ with an estimated value of 12 920 ± 50 cm⁻¹.
