In this chapter, the basic principle, instrumentation, and the analytical potential of resonance Raman spectroscopy (RRS) have been highlighted. The basic principles of Raman and RRS are discussed in the light of Albrecht's "A" and "B" terms. Advancement in Raman instrumentation, after the ...
Resonance Raman (RR) spectra of (E)-2-methyl-1,3,5-hexatriene [(E)-2-MHT], (E)-4-deuterio-2-methyl-1,3,5-hexatriene, (Z)-2-methyl-1,3,5-hexatriene [(Z)-2-MHT], (E)-3-methyl-1,3,5-hexatriene [(E)-3-MHT], and (Z)-3-methyl-1,3,5-hexatriene [(Z)-3-MHT]...

Raman Spectroscopy Detection is based on observing scattered light which can be attributed to the various vibrational energy modes of a target molecule. – No sample preparation needed – Provides real-time detection – Can provide chemical and structural information of a molecule – Can identify mole...
Meanwhile, the same design principle could be utilized in the infrared, for example, at telecom wavelengths, where much narrower spectral features can be anticipated. CONCLUSIONS In summary, we have demonstrated a new class of reflective metasurfaces based on Fano-resonant nanostructures for narrowband...
the less important is that structure to the general description of the molecule. According to the variation principle, the energyEcalculated through an optimal linear combination of wave functions for structuresiis less than the energyEiof any individual structure. The minimum value of the difference...
The optical absorption coefficient for subgap electronic transitions in crystalline and disordered semiconductors is calculated by first-principles means with use of a variational principle based on the Feynman path-integral representati...

Magnetic excitations in the 3D-AFM-ordered state of CrCl\(_3\)were studied by broad-band AFMR spectroscopy in Ref. [21] for the external magnetic field applied in theab-crystal plane. Since CrCl\(_3\)in the ground state can be viewed as a two-sublattice collinear antiferromagnet, two ...
potential energy (+31.6 mEh). The remaining 11% resulting from orbital contraction lead—of course—to an overall increase of the kinetic energy. Yet, the nature of resonance remains essentially kinetic, justifying the discussion of the probabilistic barrier as the fundamental principle of ...
3.3 Surface plasmon fluorescence spectroscopy Surface plasmon resonance fluorescence spectroscopy (SPFS) works on a similar principle to SPR, the only difference is that SPFS uses fluorescence to detect the analyte. Lakshmipriya et al.31 have detected intact influenza B virus and HA protein of influen...
