Once the length of the key string of a Vigenère cipher is known, explain how to determine each of its characters. Assume that the plaintext is long enough so that the frequency of its letters is reasonably close to the frequency of letters in typical English text.
Note Set #10 – week 12 Analytical Chemistry SPECTROSCOPY CONT. Raman Spectroscopy: the predominant form of IR spec today, extremely diverse uses, and simple to do o Raman’s original experiment: filters only violet light from the sun onto sample using telescope, then scattered light is filtered to only pass green light into detector, in his case, his own eye. o Does NOT analyze an absorption/emission event, only scattering o Raleigh scattering: the majority of light (photons) emitted from a vibrational spectrometer is the same wavelength as the light that originally went in Stokes scattering: the energy of scatted light is weaker than incident
