What is the role of intramolecular charge transfer in the dissociative photoionization of methyl iodide (CH3I)?

Label:chem

Topic
The study demonstrates that an intramolecular charge transfer occurs simultaneously with the internal conversion process, leading to the formation of methyl ions (CH3+).

From: "Evidencing an elusive conical intersection in the dissociative photoionization of methyl iodide", Chemical Science, Volume 15, Issue 9, 28 February 2024, Pages 3203-3213
Answer
The intramolecular charge transfer plays a crucial role in the dissociative photoionization of methyl iodide (CH3I) by facilitating the transfer of electronic density from the iodine atom to the methyl group, leading to the formation of methyl ions (CH3+).
