Abstract:

The imidogen radical NH is a species of fundamental scientific interest. NH is closely analogous to the isoelectronic triplet species CH2 and ground state O 3P, which have received a great deal of attention. Also, because NH has a relatively small number of electrons, its electronic structure and properties are amenable to calculation. However, aspects of the dynamics of NH remain poorly understood. NH is known to play an important role in the combustion of nitrogenous materials, such as hydrazine fuels. NH has also been observed in astrophysical object, including comets and certain types of stars. Thus, knowledge of NH reaction dynamics is needed to characterize NH in numerous chemical and physical processes.
