Abstract
Evidence for a linear dimer $Li_{2}F_{2}$ has been obtained by extending the spectral measurements for matrix isolated lithium fluoride into the far infrared region. The vapors from solid $^{6}LiF, ^{7}LiF$, and $^{6}LiF/^{7}LiF$ mixtures were deposited in argon matrices at liquid hydrogen temperatures. Vibrational assignments were made on the basis of the following linear species: $^{6}Li_{2}F_{2}, ^{7}LiF_{2}, ^{6,7}Li_{2}F_{2}$ and $^{7,6}Li_{2}F_{2}$. Although the specific geometry of the dimer could not be determined, a normal coordinate analysis supported the spectral interpretation of a linear structure $(C_{\infty v})$.
