摘要: Abstract Velocity modulation and magnetic methods as a means of selective ionic species have been applied for the first time to emission spectroscopy using grating spectrometer. Magnetic can achieve concentration effects up 100% such N 2 + at all spectrometer resolving powers. Both neutral may be modulated but depth depends in non-trivial way on discharge conditions region being observed. contrast is highly ion specific strongly power used. Ion spectra both techniques observed CO UV far-UV regions.
