For CARS, which statement is not true regarding its advantages? a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging. b) Stronger signals than spontaneous Raman. c) Suffers from fluorescence interference, because CARS signal is at high frequency. d) Faster, more efficient imaging for real-time analysis. e) Higher resolution than spontaneous Raman microscopy.

b) What is the major instrumentation advantage of Raman Spectroscopy over IR spectroscopy?

In IR spectroscopy,  please shortly explain what is Detector?  How a detector works in IR spectroscopy?  Please shortly answer at your own words.

Match the spectrophotometry term with its description. describes the relationship between the sample concentration and absorbance collected at a constant excitation wavelength while varying the emission wavelength Answer Bank emission spectrum nonradiative transition between states with the same quantum number (S Beer-Lambert law to So) fluorescence photonic emission from a molecule that has a lifetime of 10-8 to 10¬4 s molar absorptivity collected at a constant emission wavelength while varying the excitation wavelength phosphorescence molecular light emission that occurs during a transition between states o intersystem crossing different spin (triplet to singlet) internal conversion nonradiative transition between states with different quantum numbers ( to So) excitation spectrum a characteristic of a molecule that describes how much light it absorbs at a given wavelength in a particular solvent

10. The Raman spectroscopy instrument records data and then plots signal intensity vs. raman shift. What are the actual wavelengths that are (1) emitted by the laser within the instrument that is directed at the sample and (2) that are sent back to the instrument due to a Raman interaction with your sample of dry ice that has a Raman active IR band at 1300 cm³¹.

Chemistry Do the UV-vis and Fluorescence excitation spectra look alike? Why or why not?

Need help with this question. Thank you :)

the shielding in NMR is: a) Place a metal around the sample tube before staining it on the instrument.b) use a metal block to avoid being attacked by an opponentc) blocking the view of a participant in a concertd) when the magnetic moment of an atom blocks the induced magnetic moment of neighboring nuclei

What molecule does this IR sprectrum show? Please explain how you got this answer.  Thank You!
