The hyperfine structure was resolved and accurate fine and hyperfine parameters were obtained. Insights into the bonding character can be gleamed from the hyperfine constants, and an estimate of the position of two low-lying interacting electronic states can be obtain from the fine structure parameters. Details of these results will be discussed.
