Abstract: It has been shown for the first time that under the action of light within the absorption band of dimethyl ether radical cations in freon matrices [λ_max ≅ 436 nm, ϵ_max ≅ (2.5±0.5)×10³ M^–1 cm^–1], the radical cations decay due to charge transfer to freon molecules, whereas in an SF₆ matrix they undergo deprotonation with quantum yields Φ ≅ (4–15)×10^–2 and Φ ≅ (2–6)×10^–4, respectively, at 77 K.
