N2 - Excitation of the A 3Πi, state of ND in solid krypton results at temperatures ≥ 8 K in an efficient nonradiative relaxation cascade via the singlet states, populating eventually the υ″ = 5 X 3Σ- level. Subsequent relaxation is partially radiative, due to the inefficient nonradiative vibrational relaxation (υ = 1 X 3Σ-, τ = 210 ms), and the 5-4, 4-3, 3-2, 2-1, 1-0 infrared emission bands are observed. The emission structure suggests a relatively free rotation in annealed matrices, but is indicative of defect and impurity induced barriers to rotation in freshly deposited samples.
