Popis:	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, e max ≅ (2.5±0.5) x; 10 3 M -1 cm -1 ], the radical cations decay due to charge transfer to freon molecules, whereas in an SF 6 matrix they undergo deprotonation with quantum yields Φ ≅ (4-15) x;10 -2 and Φ ≅ (2-6) x; 10 -4 , respectively, at 77 K.
