Observations of the spectrum of Nova Cyg 1975 in the region from 6000 to 11,000 A are presented, consisting of photoelectric scans made on September 3-4 and 18-19, 1975, and spectrograms taken on September 25-26, 1975. For most of emission lines identified in the spectrum, the absolute flux and equivalent width are determined. The emission-line spectrum of the nova obtained on September 3-4, 1975, was due to H I, He I, N I, O I, C I, and S I. The forbidden lines of N I, O I, O II, and S III marking the nebular stage of the nova appeared in the spectrum of September 18-19, 1975.
