The decomposition of cyclobutyl chloride following multiple infraredphoton excitation has been investigated. The primary photolysis products are butadiene, from elimination of HCl, and ethylene and vinyl chloride, fromring scission. The vinyl chloride undergoes secondary decomposition to acetylene and HCl. In addition to these products, known from thermal VLPP experiments, we also find 1‐butene, which may arise from a higher energy CCl homolysis channel. Collisions with either reactant molecules oradded buffer gas lead to cooling of the laser‐produced vibrational energy distributions. The average amount of energy removed per collision is 15–20 kcal/mol for self‐collisions and 2–4 kcal/mol with argon.
