FTIR studies and UB3LYP/6-31G* calculations showed that triplet nitreno-1,3,5-triazines with zero-field splitting D-parameters of --tD/hc\ > 1.40 cm(-1) and spin populations on the nitrene centres of rho(N) > 1.77 are photochemically very stable and do not rearrange into ring-expanded products on photolysis in cryogenic matrices.
