Spectral-function sum rules for broken SU(4) symmetry are used to obtain the current-mixing angles for the vector mesons $\omega$, $\phi$, and $\psi \mathrm{}\left(3095\right)\mathrm{}$ and the mass relations among the 16 vector mesons, from which the masses of the $F^{*}$ and $D^{*}$ mesons are determined. In addition, the electron-pair partial widths of the neutral vector mesons are given.
