The spectra of the O<sub>12</sub> branch belonging to the NO γ(0, 0) band have been observed by means of single-beam twophoton excitation at high temperature. Some spectral lines that were not seen at room temperature were observed. The wavelengths of the dye laser, which is a light source for two-photon excitation, were measured, and various constants for NO molecules were evaluated.
