The electronic structure of the diamond C(100)-(2 {times} 1)/(2 {times} 2) has been investigated by means of angle-resolved photoelectron spectroscopy for the first time. A surface-related shift has been observed in the C 1s core level spectrum. The surface-state band dispersion was measured along the symmetry axis {Gamma}-J{prime} in the surface Brillouin zone. For k{sub {parallel}} = 0, there is a very pronounced surface state 1.5 eV below Fermi level E{sub F}, and it disperses downwards with increasing k{sub {parallel}}. Near the boundary of the surface Brillouin zone J{prime}, we find two states with binding energies of 1.9 and 2.4 eV with respect to E{sub F}.
