Txoj kev qub tshaj plaws thiab meej tshaj plaws ntawm X-ray crystallography yog ib leeg-crystal X-ray diffraction, nyob rau hauv uas ib tug nqaj ntawm X-rays ntaus ib tug siv lead ua, ua kom tawg. kab teeb. … Cov atoms hauv cov siv lead ua tsis zoo li qub, tab sis oscillate txog lawv txoj haujlwm txhais tau tias, feem ntau tsawg dua li ob peb feem kaum ntawm ib qho angstrom.
YPuas X-ray crystallography tib yam li qhov txawv?
2. Kev Taw Qhia • X-Ray Crystallography yog cov txheej txheem siv los txheeb xyuas cov qauv atomic thiab molecular ntawm cov siv lead ua, uas cov crystalline atoms ua rau cov teeb meem ntawm X-rays mus rau ntau qhov kev qhia tshwj xeeb. … Qhov no tsim ib tug qauv, hom qauv no hu ua X-ray diffraction qauv.
X-rays siv diffraction?
X-ray diffraction (XRD) tso siab rau ntawm ob nthwv dej / qhov xwm txheej ntawm X-ray kom tau txais cov ntaub ntawv hais txog cov qauv ntawm cov ntaub ntawv crystalline. Ib qho tseem ceeb ntawm kev siv cov txheej txheem yog qhov kev txheeb xyuas thiab cov yam ntxwv ntawm cov khoom sib txuas raws li lawv cov qauv diffraction.
YPuas X-ray diffraction spectroscopy?
Feem ntau X-ray diffraction hauv spectrometersyog ua tiav ntawm cov muaju, tab sis hauv Grating spectrometers, X-rays tawm ntawm tus qauv yuav tsum dhau qhov kev txiav txim siab, tom qab ntawd kho qhov muag cov khoom (daim iav thiab / lossis gratings) disperse lawv los ntawm diffraction raws li lawv lub wavelength thiab, thaum kawg, ib tug ntes tau muab tso rau ntawm lawv …
Dab tsi yog qhov txawv ntawm X-ray diffraction thiab diffraction?
Qhov sib txawv tseem ceeb ntawm X ray diffraction thiab electron diffraction yog qhov X ray diffraction cuam tshuam nrog qhov sib txawv ntawm qhov xwm txheej ntawm X rays mus rau ntau qhov kev taw qhia whereas electron diffraction cuam tshuam ntawm electron beam… Lwm cov txheej txheem no yog neutron diffraction.
