A preliminary investigation into the spectroscopic properties of europium monofluoride has commenced. At present, high resolution spectra have been obtained for a series of transitions in the 570 - 670 nm region. Preliminary assignments indicate that these electronic transitions are originating in one of two low-lying electronic states spaced by approximately $1400cm-1$. Comparison with previous work indicates that these states, assigned as the ground and first excited states, are both arising from same electron configuration of the europium ion $(Eu+(f7s))$. Results and analysis of the ongoing investigation will be presented and discussed in terms of the electron configurations of the various observed states.
