Optical Fiber Raman Spectra of CCl₄

Raman spectra of CCl₄ is enhanced by a factor of 10²-10³ by means of hollow core quartz optical fiber filled with binary solution containing CCl₄. The concentration of CCl₄ in solution affects on Raman scattering coefficient of CC1₄ also on aperture angle of liquid core optical fiber. For each kind of solution filling the hollow core optical fiber there is an optimum CC1₄ concentration corresponding to a maximum Raman spectra of CCl₄.
