✦ Synopsis

Excitation spectra of the total emission intensity of NO doped into solid and liquid argon and krypton are reported. The emission intensity decreases as the temperature of the triple point is approached and disappears during the solid-liquid transition. The quenching efficiency IS explained in terms of the diffusion of the long-lived a 411 valence state and its subsequent quenching, most probably, by a ground-state NO molecule. These results are exploited for a determination of the activation energy for the diffusion of the excited molecule in solid argon in the temperature range 67 < T< 83 K.
