The widely accepted mechanism of formation for carbon-centered radicals in the gas-phase cigarette smoke involves reactions of NO(2) and alkadienes. However, specific examples of such radicals have never been isolated from fresh cigarette smoke or their structure determined. We have identified two previously unrecognized classes of carbon-centered radicals, alkylaminocarbonyl and acyl radicals, that are unrelated to radicals that form by NO(x) chemistry. The combined abundance of these… CONTINUE READING
