Abstract

Influence of molecular structure of high-energy molecules on their collisional relaxation behavior was investigated using high-resolution transient infrared absorption spectroscopy. State resolved energy transfer was studied from highly vibrationally excited picoline (2-methylpyridine) and lutidine (2,6-dimethylpyridine) to carbon dioxide molecules by measuring the energy partitioning in the scattered carbon dioxide molecules. It was found that the largest energy exchanges resulted from impulsive collisions of the hot donor with carbon dioxide. The scattered carbon dioxide molecules were characterized by correlated rotational and translational excitation.
