Txawm li cas los xij, Stokes kab yog qhov sib piv nrog cov neeg tiv thaiv Stokes, vim lub xeev hauv av vibrational muaj neeg coob dua li cov xeev txaus siab.
Vim li cas kev siv ntawm Stokes cov kab ntau dua?
Raws li tus naj npawb ntawm atoms hauv lub xeev hauv av yog ntau dua li cov atoms hauv lub xeev zoo siab, cov kab Stokes muaj zog dua li cov kab tiv thaiv Stokes.
Vim li cas cov kab tiv thaiv Stokes tsis tshua muaj zog?
Tsis tas li, nco ntsoov tias txoj kab tiv thaiv Stokes tsis tshua muaj zog dua li Stokes kab. Qhov no tshwm sim vim tsuas yog cov molecules uas vibrationally zoo siab ua ntej irradiation tuaj yeem ua rau cov kab tiv thaiv Stokes.
Cov kab twg mob siab tshaj?
Cov kab hauv qab no twg yog qhov khaus tshaj? Nqe lus piav qhia: Cov Rayleigh-scattered radiationsyog qhov khaus ntau dua li ntawm ob hom - Strokes kab thiab Anti-Strokes kab.
Cov kab Stokes txawv ntawm cov kab tiv thaiv Stokes li cas?
Stokes kab yog ntawm lub wavelength ntev dua li ntawm cov hluav taws xob txaus siab rau lub luag haujlwm rau fluorescence lossis Raman nyhuv. … Yog li, cov kab tiv thaiv Stokes yeej ib txwm muaj luv luv wavelength tshaj li lub teeb uas ua rau lawv.
