Temperature-dependent photodissociation dynamics of ICN at 262 nm Academic Article uri icon

abstract

  • Transient frequency-modulation (FM) Doppler spectroscopy has been used to measure scalar and vector correlations in state-selected CN fragments arising from the photodissociation of ICN at 262 nm at both 296 and 550 K. We find that the state-selected I*/I branching ratio changes significantly with increased temperature, consistent with the increased width of the state-dependent CN rotational distribution. However, we find little change in the state-selected vector properties suggesting that thermal modification of the initial parent vibrational distribution is not a sensitive means to probe the nonadiabatic dynamics. 2001 Elsevier Science B.V.
