Vibronic spectrum of jet-cooled 2-chloro-5-fluorobenzyl radical: Assignments and substituent effect

- We generate jet-cooled 2-chloro-5-fluorobenzyl radical by corona discharge of precursor 2-chloro-5-fluorotoluene.
- We determine the electronic transition energy and vibrational mode frequencies.
- We discuss the unusual red-shift of electronic transition energy.
