dc.description.abstractThe absorption spectrum of $F_{2}$ in the vacuum ultraviolet region has been photographed at a sufficiently high resolution to permit the rotational analysis of many bands. The lowest state observed is a $^{1}\Sigma^{+}_{u}$ valence state which gives a large number of perturbed bands in the 1000 {\AA} region. The spectrum of F$_{2}$ at liquid nitrogen temperature shows many weak bands of a second band system in the same region which also appears to be a $^{1}\Sigma^{+}_{u}$-X$^{1}\Sigma^{+}_{g}$ system. The upper state vibrational levels of this weak system have B values in the 0.18 cm$^{-1}$ range and it can be shown that they are responsible for most of perturbations in the stronger system. The problems in assigning the excited states will be discussed. Many bands of the strong $^{1}\Sigma^{+}_{u}$-X$^{1}\Sigma^{+}_{g}$ system have been observed in emission in the 1100 {\AA} region. An analysis of these emission bands has allowed us to determine the energies and B values of 23 vibrational levels of the ground electronic state. The RKR potential curve of the ground state and an improved value of the dissociation energy have been determined.en_US
