The energy diagram and spectral assignment of the observed spectrum. (a) and (b) Level schemes for the V₁ and V₂ velocity groups, respectively. The blue solid line indicates the couple beam frequency ω_c locked at the F = 2 to F′ =CO₁₋₂ while the weak (red colored) line indicates the probe beam scanning from the ground level F = 1 to the excited level F′ = 0,1,2. (c) and (d) Level schemes showing the formation of the EIT for V₁ and V₂ velocity groups.
