Webbluminescence spectrum when illuminated with the Raman excitation laser. The shape of the luminescence spectrum is described by a polynomial expression that relates the relative spectral intensity to the Raman shift with units in wavenumber (cm 1). This polynomial, together with a measurement of the luminescence spectrum of the standard, …
Webb17 dec. 2015 · In the raw data, intensity values (i.e. the color scales of Raman maps) are expressed in arbitrary units (i.e. detector counts), which are specific to our instrument configuration. Webb16 mars 2024 · The intensity of the three anti-Stokes lines drops going from the 218 to 314 to 459 cm -1 band. Anti-Stokes scatter requires an interaction of the incident photon with vibrationally excited molecules. Heat in the system causes some molecules to be vibrationally excited.
