 Title: STATE SELECTED PHOTODISSOCIATION $(B{^{1}}\Pi_{u} \leftarrow X{^{1}}\Sigma^{+}_{g})$ IN $K_{2}$ BY ALL-OPTICAL TRIPLE RESONANCE SPECTROSCOPY Creators: Ji, B.; Yiannopoulou, A.; Wang, J. X.; Wang, H.; Kleiber, P. D.; Lyyra, A. M.; Sando, K. M.; Stwalley, W. C. Issue Date: 1993 Publisher: Ohio State University Abstract: Final state analysis of the products of molecular photodissociation gives information about the dynamical evolution of the system from short to long range including information about nonadiabatic interaction between potential energy curves and the transition through different angular momentum coupling regions [1]. Applying the all-optical triple resonance (AOTR) technique, specific individual rovibrational levels in $K_{2}$ are selectively photodissociated [2]. Polarization of the resulting atomic fluorescence is measured and analyzed by multichannel quantum defect-half collision theory [3]. Description: [1] P. D. Kleiber, J. X. Wang, K. M. Sando, V.
