LADP-3 Microwave Electron Spin Resonance Mea Hana
Kapa ʻia ka resonance electron spin resonance electron paramagnetic, kahi e pili ana i ka hanana o ka hoʻololi resonance ma waena o nā pae ikehu manamana o ka uila uila i ka manawa e hoʻopili ʻia e ka nalu electromagnetic e like me ka pinepine i ka pā magnet. Hiki ke ʻike ʻia kēia hanana i loko o nā mea paramagnetic me nā manawa ʻume mākenēki ʻole pālua (ʻo ia hoʻi nā mea hoʻohui i loaʻa nā electrons uncoupled). No laila, he mea nui ka resonance spin electron e ʻike ai i nā electron uncoupled i loko o ka mea a me kā lākou launa pū ʻana me nā ʻokoma e hoʻopuni ana, i loaʻa ai ka ʻike e pili ana i ka microstructure o nā mea. He kiʻina kiʻekiʻe a me ka hoʻonā ʻana kēia ʻano, a hiki ke hoʻohana ʻia e kālailai i nā mea i ke kikoʻī me ka ʻole o ka hōʻino ʻana i ke ʻano o ka laʻana a ʻaʻohe mea e hoʻopilikia ai i ka hopena kemika. I kēia manawa, hoʻohana ākea ia i ka noiʻi o ka physics, kemika, biology a me nā lāʻau.
Nā hoʻokolohua
1. E hoʻopaʻa a hoʻomaopopo i ka hanana uila resonance uila.
2. Ana iā Lande's g-kumu o ka hāpana DPPH.
3. E aʻo pehea e hoʻohana ai i nā mīkini uila i ka ʻōnaehana EPR.
4. Hoʻomaopopo i ka nalu kū i ka hoʻololi ʻana i ka lōʻihi o ka lua resonant a hoʻoholo i ka nalu lōʻihi o ka nalu.
5. E ana i ka hoʻolaha ʻana o ka nalu e kū nei i ka lua resonant a hoʻoholo i ka nalu o ka nalu.
