The effects of isolated nitrogen impurities on the bulk phonon spectrum of synthetic diamond are investigated using a model in which the nitrogen atom is part of an eight-atom impurity cluster in the lattice. Good agreement with experimental results is obtained. The physical basis for the unusual isotope-dependent behavior of two prominent impurity modes is determined.
