X-rays range in wavelength from 10 to 0.01 nanometers; a typical wavelength used for crystallography is 1 Å, which is on the scale of covalent chemical bonds and the radius of a single atom. Therefore, X-rays are the \"sweet spot\" for wavelength when determining atomic-resolution structures from the scattering of electromagnetic radiation. The most precise method of X-ray crystallography is single-crystal X-ray diffraction, in which a beam of X-rays strikes a single crystal, producing scattered beams. When they land on a piece of film or other detector, these beams make a diffraction pattern of spots; the strengths and angles of these beams are recorded as the crystal is gradually rotated. X-ray diffraction data can determine the mean chemical bond lengths and angles to within a few thousandths of an Angstrom and to within a few tenths of a degree, respectively.Data are combined computationally with complementary chemical information to produce and refine a model of the arrangement of atoms within the crystal.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659622359\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659622359","offer_id":39441129603165,"sku":"9783659622359","price":61.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/1ece65fe-4ba9-4fb0-a256-9afd24cb0f1f.jpg?v=1757654598","url":"https:\/\/shop.autorenwelt.de\/products\/crystalstructure-quantum-calculations-of-sulfamerazine-polymorph-iii-von-mahesh-k-patel-kinjal-d-patel-u-h-patel","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
