Thawj spectroscope tau tsim nyob rau hauv 1814 los ntawm tus kws kho lub cev thiab lub lens tsim Joseph von Fraunhofer. Xyoo 1859, German chemist Robert Wilhelm Bunsen thiab physicist Gustav Robert Kirchhoff siv nws los txheeb xyuas cov ntaub ntawv uas tawm lub teeb thaum rhuab.

Leej twg nrhiav tau spectroscopy?

Feem ntau, Sir Isaac Newton tau lees paub nrog qhov kev tshawb pom ntawm spectroscopy, tab sis nws txoj haujlwm yuav ua tsis tau yog tias tsis muaj kev tshawb pom los ntawm lwm tus ua ntej nws.

Lub spectroscope siv nyob qhov twg?

Spectroscopes feem ntau yog siv hauv astronomy thiab qee ceg ntawm chemistryCov spectroscopes thaum ntxov tsuas yog prisms nrog kev kawm tiav uas cim wavelengths ntawm lub teeb. Niaj hnub nimno spectroscopes feem ntau siv ib tug diffraction grating, ib tug movable slit, thiab ib co hom ntawm photodetector, tag nrho cov automated thiab tswj los ntawm lub computer.

Leej twg siv spectroscopy?

Spectroscopy yog siv hauv lub cev thiab tshuaj ntsuam chemistry vim tias atoms thiab molecules muaj qhov tshwj xeeb spectra. Yog li ntawd, cov spectra no tuaj yeem siv los txheeb xyuas, txheeb xyuas thiab txheeb xyuas cov ntaub ntawv hais txog cov atoms thiab molecules. Spectroscopy kuj tseem siv nyob rau hauv astronomy thiab tej thaj chaw deb sensing ntawm lub ntiaj teb.

3 yam yooj yim ntawm spectroscopy yog dab tsi?

Lub hom phiaj tseem ceeb ntawm atomic spectroscopy suav nrog atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES) thiab atomic fluorescence spectroscopy (AFS). Hauv AAS atoms nqus ultraviolet lossis pom lub teeb kom hloov mus rau qib siab zog.
