Lub sijhawm niaj hnub ntawm cov organic photochemistry pib nyob rau hauv 1866, thaum Lavxias tus kws kho mob Carl Julius von Fritzche pom tias cov tshuaj anthracene concentrated raug rau UV hluav taws xob yuav poob los ntawm kev daws raws li nag lossis daus..
photochemistry siv rau dab tsi?
Photochemistry yog kev kawm txog cov txheej txheem tshuaj uas tshwm sim vim qhov nqus ntawm lub teeb. Kev kawm txog cov tshuab photochemical uas siv lub hnub ci los tsav cov tshuaj lom neeg tseem ceeb lossis tsim hluav taws xob yog qhov tseem ceeb rau kev txhim kho cov peev txheej ntawm lub zog.
Lub hauv paus ntsiab lus ntawm photochemistry yog dab tsi?
Thawj txoj cai ntawm photochemistry, lub npe hu ua Grotthuss-Draper txoj cai (rau chemists Theodor Grotthuss thiab John W. Draper), hais tias lub teeb yuav tsum tau nqus los ntawm cov tshuaj lom neeg txhawm rau txhawm rau photochemical. kev tshwm sim tshwm sim.
Einstein txoj cai lij choj ntawm kev sib npaug ntawm cov duab hluav taws xob yog dab tsi?
Raws li txoj cai no, ib lub molecule yog qhib los ntawm kev nqus ntawm ib qho quantum ntawm hluav taws xob hauv thawj (lossis thawj) cov kauj ruam ntawm cov tshuaj tiv thaiv photochemical. Txoj cai no, txawm li cas los xij tsis txhais tau hais tias ib qho molecule yuav tsum ua rau txhua lub photon absorbed.
grothus Draper law yog dab tsi?
Ib txoj cai lij choj hauv photochemistry hais tias tias tsuas yog lub teeb uas nqus los ntawm cov khoom lossis cov khoom muaj txiaj ntsig hauv kev coj cov tshuaj hloov pauv. Tsis yog txhua lub teeb poob rauCov tshuaj yuav tsum ua rau muaj kev hloov tshuaj lom neeg, vim qee qhov ntawm nws tuaj yeem rov ua dua nyob rau hauv daim ntawv ntawm tshav kub lossis lub teeb.
