| Abstract: | The vibrational analysis of the CN(B2Σ+ → X2Σ+) emission sensitized by Hg(63P0) metastables has shown that the energy transfer process, Hg(63P0) + CN(X2Σ+) → Hg(61S0) + CN(B2Σ+), populates the CN(B2Σ+) state in a non-Franck-Condon fashion. The relative vibrational populations for the ν = 0 to 4 states are 1.00, 0.56 ± 0.06, 0.26 ± 0.03, 0.11 ± 0.03 and 0.04 ± 0.01, respectively. Long-range attractive interaction between the Hg(63P0) atom and the CN(X2Σ+) radical is evidenced by the observed high rotational excitation of the CN(B2Σ+) radical following the energy transfer process. |
