抄録: | Styrene was irradiated at-196°C to give a five-line spectrum with a coupling constant of about 16 gauss. This is attributed to the free radical When a mixture of styrene and 2-methyltetrahydrofuran was irradiated, a broad singlet spectrum (total width 33 gauss) was superposed on the seven-line spectrum due to the methyltetrahydrofuran radical and no sharp singlet spectrum due to trapped electrons was observed. This broad singlet spectrum is thought to be due to styrene anion radicals. This spectrum was bleached by visible light and saturated appreciably with increasing microwave power. Similar phenomena were observed for a styrene-3-methylpentane mixture. |
