We have studied the fate of selectively excited vibrational and rotational NH/ND(c(1) Pi,nu,J) states in inelastic collisions with O-2, The excited states were produced in a two-step procedure by first photolyzing hydrazoic acid to yield NH/ND(a), which then was excited to the c state. This work presents rate data for rotational relaxation in the c,nu=0 states, overall quenching of rotational states, intersystem crossing to the A(3) Pi state, vibrational relaxation of the ND(c,nu=1) state, and quenching of the vibrational ND(A,nu=0-3) states. Additionally the vibrational distributions of the A state products were determined as a function of rotation of the c states.
