Characterization of Tetrahydrogen via State-Selected Excitation of H2

Abstract

The initial effort to detect tetrahydrogen formed in a supersonic of jet expansion was unsuccessful; the lifetime of tetrahydrogen was too short to permit detection. A study of the high-spin quintet nitrogen system was also conducted. Production of the A'-state was observed from energy pooling of triplet A-state molecules. Based on simple kinetic arguments, an upper limit of the lifetime of the A'-state was set at 0.3 ms.
