High-resolution electronic spectroscopy was performed on AuF. The rotational, vibrational, electronic and hyperfine structure was resolved. Through detailed analysis, several vibrational bands of the [17.7]1-X1Σ+ and [17.8]0 - X1Σ+transitions were assigned. At least squares fit of the data collected by laser excitation spectroscopy from the transitions has provided the most accurate determination of the rotational, vibrational and electronic constants of the [17.7]1 and [17.8]0 states for AuF to date. Subsequent efforts in hyperfine analysis showed a discrepancy in the original assignment of the [17.7]1 state. Through application of quantum mechanics, the correct assignment of 3Δ1 state mixed with a lower-lying 1Π1 state was realized.
