The laser-induced fluorescence method is used to measure the radiative lifetimes and emission branching fractions in six levels in V II. The emission branching fractions were determined for an additional 17 V II levels with known lifetimes. Also, 14 V II transition probabilities were measured with an inductively coupled argon plasma spectral source in which the level populations vary with level excitation energy in a predictable way. The equivalent widths of V lines were measured and the solar V abundance was calculated with the models of Holweger-Mueller (1974) and Maltby et al. (1986). It is found that the mean solar V abundance, base on V I and V II lines is 4.00 + or - 0.02.
