摘要: Deuterated naphthalene in deuterated durene (DD) was observed to have an extraordinarily intense paramagnetic resonance signal relative ordinary (HH). Decays of the magnetic resonances after cessation ultraviolet irradiation were examined at 77 deg K and found obey exponential decay law with a mean life 2.1 plus or minus 0.1 sec for HH 16.9 0.7 DD. The (HD) differ by less than 0.5 from that HH. also studied static field along two principal axes all three variation lifetime direction nil. showing change lifetinne is purely mass effect rather nuclear hyperfine effect.
