We describe searches for B meson decays to the charmless vector-vector final states ωK* and ωρ in 89 × 10<sup>6</sup> BB̄ pairs produced in e<sup>+</sup>e<sup>-</sup> annihilation at √s = 10.58 GeV. We measure the following branching fractions in units of 10 <sup>-6</sup>: B(B<sup>0</sup> → ωK*<sup>0</sup>) = 3.4 <inf>-1.6</inf><sup>+1.8</sup> ± 0.4(<6.0), B(B<sup>+</sup> → ωK*<sup>+</sup>) = 3.5<inf>-2.0</inf><sup>+2.5</sup> ± 0.7(<7.4), B(B<sup>0</sup> → ωρ<sup>0</sup>) = 0.6 <inf>-1.1</inf><sup>+1.3</sup> ± 0.4(<3.3), and B(B<sup>+</sup> → ωρ<sup>+</sup>) = 12.6<inf>-3.3</inf><sup>+3.7</sup> ± 1.6. The first error quoted is statistical, the second systematic, and the upper limits are defined at 90% confidence level. For B<sup>+</sup> → ωρ<sup>+</sup> we also measure the longitudinal spin alignment fraction f<inf>L</inf> = 0.88<inf>-0.15</inf><sup>+0.12</sup> ± 0.03 and charge asymmetry A<inf>ch</inf> = (5 ± 26 ± 2)%. © 2005 The American Physical Society.
