Txoj kev lej twg yog siv hauv X-ray crystallography? Nqe lus piav qhia: Hauv X-ray crystallography, cov duab ob-dimensional tsim tau hloov mus rau hauv peb-dimensional daim ntawv siv lub tswv yim lej of Fourier transformation.

X-ray crystallography yog dab tsi?

X-ray crystallography yog txheej txheem uas relies ntawm kev cuam tshuam ntawm electromagnetic hluav taws xob nyob rau hauv thaj tsam ntawm 0.01–10 nm (txawm tias feem ntau 0.05–0.3 nm) nrog cov teeb meem hauv crystalline daim ntawv kom cov qauv ntawm crystallized molecules tuaj yeem txiav txim siab nrog kev daws teeb meem rau lawv tus kheej atoms.

Txoj kev twg yog siv rau X-ray diffraction?

X-ray diffraction yog raws li kev cuam tshuam ntawm monochromatic X-rays thiab cov qauv crystalline. Cov X-rays no yog tsim los ntawm cathode ray raj, lim los tsim cov hluav taws xob monochromatic, collimated kom mloog zoo, thiab coj mus rau cov qauv.

Txoj cai twg yog siv hauv xray crystallography?

Cov qauv ntawm cov muaju thiab cov molecules feem ntau raug txheeb xyuas siv cov kev tshawb fawb x-ray diffraction, uas tau piav qhia los ntawm Bragg Txoj Cai. Txoj cai lij choj piav qhia txog kev sib raug zoo ntawm lub teeb x-ray tua rau hauv thiab nws qhov kev xav tawm ntawm lub ntsej muag siv lead ua.

Yuav ua li cas yog txoj kev X ray crystallography siv?

Lub hom phiaj ntawm x ray crystallography yog kom tau txais peb qhov qauv molecular los ntawm cov siv lead ua. Cov qauv purified nyob rau hauv siab concentration yog crystallized thiab cov muaju yog raug rau ib x ray beam.
