A diffuse FIR C II forbidden emission line was detected in an extensive region (l = 30-51 deg) along the Galactic plane; the line is bright and extended far from discrete luminous H II regions. The diffuse forbidden C II emission probably originates from the photodissociated C(+) regions enveloping giant molecular clouds exposed to the general interstellar ultraviolet radiation field. 51 refs.
