Popis: The line shapes of the Balmer lines ( n = 3, 4) produced from the reaction between methylene chloride and metastable helium atom He (2 3 S) in a high vacuum chamber were analyzed, and the nascent translational energies were estimated from the Doppler broadening profiles. The fractions of available energy partitioned into translational energy can be explained by a simple impulsive model incorporating vibrational excitation due to geometry change during transition from the parent to product fragments. The precursor state was assigned to a Rydberg component converging to the upper state of CH 2 Cl + 2 . Subsequent predissociation of the Rydberg state leads to the production of H*.
