We study the electronic properties of quasi-one-dimensional V6O13 which exhibits a metal-insulator transition using angle-resolved photoemission spectroscopy (ARPES), optical conductivity, and soft X-ray Raman spectroscopy (SXRS). From ARPES, we observe an energy gap of 0.2 eV across the metal-insulator transition with change in the lower Hubbard band. Band dispersion is found only along the b-axis, consistent with highly anisotropic behavior observed in optical conductivity and SXRS measured on the same samples. These results indicate the electronic properties of V6O13 are dominated by b-axis electronic structure.
