Infrared absorption spectroscopy

Infrared absorption spectroscopy yog hu ua infrared spectroscopy. Thaum muaj qee zaus ntawm lub teeb infrared irradiates ib lub molecule, yog tias qhov kev vibration zaus ntawm ib pawg hauv cov molecule zoo ib yam nrog cov zaus ntawm sab nraud infrared tawg, lub zog ntawm lub teeb hloov mus rau lub molecule los ntawm kev hloov ntawm molecular dipole lub caij. , thiab pab pawg no yuav nqus tau qee zaus. Lub teeb infrared ua rau kev vibration hloov.
