摘要：

We use the 1/N-c method to estimate electromagnetic contributions to vector meson masses and mixings. We identify several new sources of rho - omega mixing coming from short-distance effects. We comment on the extraction of quark masses from the vector meson masses. We also present a simple group theoretical discussion of the electromagnetic mass differences.
