✦ Synopsis

The A' 'Z: state of N2 was detected for the first time in a direct measurement, using a high-resolution laser absorption technique within the C" 'lI. +A' 'Z: (u' =O+Y" =O) band. Evidence is given that the quintet state was created by means of an energy pooling reaction from the A '2: state in a pure nitrogen pulsed discharge. From the absolute density measurements of the quintet A' state and its precursor triplet A state, the upper limit for the destruction rate coefficient of the A' 'C state by a ground state molecular nitrogen was estimated to bc 7 x lo-" cm3 molecule-' s-'.
