For this process, the pump laser excites polarization modes along the two … WebFeb 8, 2012 · Compound 9 shows absorption in the red-shifted range, but the Stokes shift (<30 nm) is much smaller than that for BS-SS and BS-DS. DFT calculations propose the large Stokes shifts of BS-SS and BS-DS are due to the remarkable geometry relaxation upon photoexcitation and its substantial effect on the energy levels of molecular orbitals.

WebOct 19, 2024 · The Stokes Shift is named after Irish physicist George Gabriel Stokes and is the spectral shift to lower energy between the incident light and the scattered or emitted light after interaction with a sample. The Stokes Shift is an important concept in both Fluorescence and Raman spectroscopy and is introduced in this article. WebJun 7, 2004 · Small differences between the emission and absorption spectra of three‐level maser centers can have a pronounced effect on maser operation. This paper considers the effects of a Stokes shift, the simplest and most probable difference. If there is a Stokes shift which is large compared to the linewidth, the operation of the maser will be essentially … WebThe all-important Stokes shift.
